Fashion, a means of communication, is the symbol conveying the social information and the individual identity. The opulence of material and the development of civilization make the sign of fashion variable and individual; especially, The importance of hair style among the today's sign of fashion, as a determinant element in judging each person's look is emphasized. Kitsch, based on the variety and the individuality is the manner of art in diverse hobbies. In addition, it enlarges the sphere of modern an, creates new open aesthetic world. Therefore, we need to understand the symbol of Kitsch aestetic represented in hair style, which is meaningful. The method of this study is quality analysis by means of semiology, aesthetics, Fashion artical, magazine, atc. To support this statement, we will study the form, a primary symbol, and the ideology, a secondly one in $\ulcorner$Mythologies$\lrcorner$ of Roland Bartes(1972). Then by means of the form and the ideology, we will try to recognize the myth, an essential symbol. The result of this study is following like these three points. First, the Kitsch patterns of representation in hair style use the accumulation by an excessive ornamentation; the inappropriateness by the lack of form, the disagreement, the unbalance, and the nonfunctional form; and finally, the amusement by the reconstruction, the exotic, and the satire. The above three is true to the Barthes's primary symbol-the form. Second, the anti-traditionality(including the lack of form, the disagreement, and the unbalance), the homesickness(including the reconstruction and the exotic), and the eclecticism(including the parody and the mixed imitation) are created as the ideology of the liberal artistic notion, different from the past outlooks on aesthetic. This is true to the Barthes's secondly symbol-the ideology. Third, the form and the ideology enable us to express our own thoughts and to recover the humanity, which is the primary purpose of Kitsch aesthetic. The Kitsch hair style, as we witness, does lead the varied and liberal aesthetic world, create its accessible value, and place the art of hair style in a higher status.

This study tried to improve the design of the symbol mark for the fashion industry and effectively publicize the brand image of a small fashion accessory company through a powerful visual communication strategy. For this purpose, this study performed research and an analysis of the features of existing fashion accessory companies as well as the current status and features of their utilization of symbol marks for the enhancement of the brand's image. Total 48 fashion accessory brands focued on jewerly were selected from the Dictionary of Fashion Brand and the types of symbol analyzed the concepts and formative aesthetics of the symbol mark design in each brand. Based on the data, this study designed the fashion accessory company's logo and a new symbol mark design. It makes full use of the characteristics of the logos and the symbol mark that reflect the most critical issues of fashion accessory design so as to promote the consumers' level of product recognition as well as the product symbol characteristics. In the case of combining characters with concrete objects, they were found generally to use objects that give elegance, cute and feminine images, such as rings, hearts and small pets. Moreover, colors in the series of black/grey seemed to be used to convey the concept of accessory brands that pursue modern, sophisticate, and practical images. As these design plans, enhancement of the consumers' level of recognition of the brand is attempted as well as the execution of an effective publicity of the feature of the product through the use of the logo and symbol marks reflecting the features of the fashion accessory, instead of simply introducing the brand or product. The result of this study indicates that methods to design brand symbol marks for clothing should be incessantly sought in a way to build brand power as an important component to represent concepts and reinforce brand image.

The purpose of this study is to provide color information in order to planning and merchandising in china fashion through the color of Beijing opera. In objective study, we collect total 302 Beijing opera images. The collecting method of source data is to extract digital color data by color picker. We transform RGB color data to H V/C, CIE L*a*b and analyze the attributes of color and tone, three-dimensional analysis. The results of this study are as follows : 1. The color distrbution of Beijing opera is R(26.9%)>YR(18.2%)>PB(11.6%)>Y(9.6%). Traditional preference color, red is most popular color as 26.7%:, the practice of vivid tone red is numerous. 2. The tone distribution of Beijing opera costume is P(16%)>It(13.9%)>d(11%)>5(9.6%)>4kg (8.2%)>b(7.1%:). The value o# Beijing opera costume distribute medium and medium-high and the chroma of those distributes low. 3. High chroma yellow is restrictive color as the symbol of emperor in china but medium-low chroma yellow is very frequently used. 4. Blue is often used in china costume. Especially in Beijing opera costume blue is symbol of bravery, dignity, cruel character 5. White in Beijing opera costume is much used for symbol of righteous loyalist. Black is less used than white in Beijing opera costume and black is authority color for symbol of the prime minister.

This paper contains two algorithms proposed for synchronization in OFDM system. The first is having 1 symbol offset while calculating the timing metric, and the second is introduced in new parameter such as Reduction Factor(${\rho}$), Break Constant(${\beta}_k$) and Implant Depth(${\delta}_I$) in order to control the power of CP(Cyclic Prefix) area. Two proposed method are evaluated performance with conventional methode, and than the result of simulation show proposed methods is better than conventional methode while it experience into multipath fading channel.

In this paper, a new practical coherent detection scheme for biorthogonal signals, which uses multi-symbol observation interval, is proposed and its performances are analyzed and simulated. The technique jointly estimates both the demondulated data and the channel from received signal only while reducing computation complexity by an approximate maximum-likelihood sequence estimation rather than symbol-by-symbol detection as in previous noncoherent detection. The scheme achieves performance close to that of ideal coherent detection with perfect channel estimates when select the appropriate observation symbol interval N in the given symbol alphabet wize M. What is particularly interesting is that the requeired average signal-to-noise ratio per bit ${\gamma}_{b}$ can be reducedd by as much as 1.4dB and the capacity can be increase by as much as 38% when we use this system in the CDMA cellular reverse link.

This paper considers the maximum likelihood (ML) detection of 16-ary differential amplitude and phase shift keying (DAPSK) in Rayleigh fading channels. Based on the conditional likelihood function, two new receiver structures, namely ML symbol-by-symbol receiver and ML sequence receiver, are proposed. For the symbol-by-symbol detection, the conventional DAPSK detector is shown to be sub-optimum due to the complete separation in the phase and amplitude detection, but it results in very close performance to the ML detector provided that its circular amplitude decision thresholds are optimized. For the sequence detection, a simple Viterbi algorithm with only two states are adopted to provide an SNR gain around 1 dB on the amplitude bit detection compared with the conventional detector.

In this paper, the idea of using a multiple symbol obervation interval to improve error probability performance is applied to differential detection of MTCM(multiple trellis code modulation) with ${\Pi}$/4 shift QPSK, 8DPSK and 16DPSK. We propose two types of sliding multiple symbol differential detection algorithm, type 1 and type 2. The two types of sliding detection scheme are examined and compared with conventional(symbol-by-symbol) detection and bolck detection with these modulation formats in an additive white Gaussian noise(AWGN) using the Monte Carlo simulation. We show that the amount of improvement over conventional and block detection depends on the number of phases and the number of additional symbol intervals added to the observation. Computer simulagtion results are presented for 2,4,8 states in AWGN channel.

In this paper, We present a low complexity candidate list generation scheme in iterative MIMO receiver. Since QAM modulation can be decomposed into HP symbols and LP symbol and HP symbol is robust in error capability, we generate HP symbol list with simple ZF detector output and its corresponding neighbor HP symbols, Then, based on HP symbol list, the LP symbol list is generated by using the sphere decoder. From the second iteration, since apriori value from channel decoder is available, the candidate list is updated based on demodulated apriori value. Through the simulation, we observe that at the first iteration, the BER performance is worse than LSD. However, as the number of iteration is increased, the proposed scheme has almost same performance as LSD. Moreover, the proposed one has reduced candidate list generation time and lower number of candidate list compared with LSD.

This paper proposes a symbol timing recovery method that is simple in structure and can provide high speed symbol synchronization. Transmitter and receiver are not synchronized in communication systems using digital modulation. Receiver should search the timing variation of transmitter continuously. The proposed timing recovery method searches sample position by comparing previous sample value with next sample value. This method can be applied to digital and optical transceivers with high data rate.

In this paper we describe the design of symbol timing and carrier synchronization algorithms for burst receiver. The demodulator consists of digital down converter, matched filter and synchronization circuits. For symbol timing recovery we use modified Gardner algorithm. And we use decision directed method for carrier phase recovery. For the sake of performance analysis, we compare simulation results with the board implemented by FPGA which is APEX20KE series chip for Alter. The performance results show it works quite well up to the condition that a frequency offset equal to 0.1% of symbol rate.
