  • 본 논문에서는 무선랜 프로토콜 IEEE802.11g에서 사용되는 변조방식인 OFDM (Orthogonal frequency division multiplexing) 방식을 TMX320C6416을 사용하여 구현하였다. 통신 시스템의 발달에 따라 고속으로 데이터를 전송하는 방식이 요구되었고, 유선망 없이 장소에 구애 받지 야고 데이터를 송수신할 수 있는 무선랜 시스템의 필요성이 증가하고 있다. 이러한 필요성에 따라 2002년 6월 현재 발표된 IEEE 802.11g 규격 Draft 2.8은 2.4GHz 주파수 대역에서 기존 IEEE 802.11b규격과 호환성은 유지하며 전송속도를 최소 20Mbps 이상을 목표로 한다. IEEE802.119에 정의된 규정에 따라 OFDM방식의 기저대역 알고리즘을 TMX320C6416 을 사용하여 각 블록별로 C언어로 구현하였고, TMX320C6416에 대한 리니어 어셈블리 언어로 구현하는 최적화 작업을 통해 연산속도를 향상시키는 것을 목적으로 하며, 구현한 알고리즘의 비트 오류 확률을 매트랩 시뮬레이션 결과와 비교해 보도록 한다.

  • Today is the Information age which Internet service acts a most important Information Source. So the Power Line Communication has been achieved to offer Internet service for Last-Mile area. And Research is achieved to frequence range from 30MHz to 80MHz for High-speed communication service. But, Power Line is not suitable for communication, So, electric wave is generated from flow of communication information. And the electric wave is interfered with Wireless Communication Service using the same frequence range. In this paper, a Notch Filter for reduce of interference between Power Line Communication and Wireless Communication Service is proposed. The proposed emulator is developed using TMS320C6416T DSP board of Texas Instruments.

  • In this paper, we address several issues in the real time implementation of MPEG-1 Layer II decoder on a fixed-point digital signal processor (DSP), especially TMS320C6416. There is a trade-off between processing speed and the size of program/data memory for the optimal implementation. In a view of the speed optimization, we first convert the floating point operations into fixed point ones with little degradation in audio quality, and then the look-up tables used for the inverse quantization of the audio codec are forced to be located into the internal memory of the DSP. And then, window functions and filter coefficients in the decoder are precalculated and stored as constant, which makes the decoder faster even larger memory size is required. It is shown from the real-time experiments that the fixed-point implementation enables us to make the decoder with a sampling rate of 48 kHz operate with 3 times faster than real-time on TMS320C6416 at a clock rate of 600 MHz.

  • Power Line Communication (PLC: Power Line Communication) to propagate the current power lines are in every household of the existing infrastructure is the most extensive network configuration. In addition, the cost required for network configuration, the advantage of almost zero for the investors and is sufficient to attract the attention of operators. The PLC is supply power to power lines used the voice and data communication technologies put it on KHz ~ tens of hundreds of high-frequency signal MHz. But because uses power lines as existing wireless communications systems will occurs interference. The notch filters of a common way to eliminate the interference are used. In this paper, a dynamic high-performance notch filter applying CIC filter performance was verified through MATLAB and was implemented using a TI's TMS320C6416T DSP board.

  • The Spectrum Sensing technology is the core technology of the Cognitive Radio (CR) system that is one of the future wireless communication technologies. This is the technology that temporarily allocates the frequency bandwidth by scanning surrounding wireless environments to keep licensed terminals and search the unused frequency bandwidth. In this paper, we implement the efficient Spectrum Sensing methods based on CR technology in an embedded board. The DVB-H signal with the 6MHz bandwidth is used as the RF input signal. And we confirm the Spectrum Sensing result using Modified Periodogram Method, Welch's Method, SCF Method. And also, We examine the execution speed of each of detailed functions and the performance of Spectrum Sensing methods on TI320C6416 DSP board inserted in an embedded board.
