Abstract
This paper presents a way to maximize transmission efficiency and reception ability through transmission diversity technology, which can be adapted to wireless multimedia OFDM (orthogonal FDM) system. The presented method gives a comparative analysis between a case where parameter a for time average is 0.3, i with consideration of channel presumption and two types of rms delayed proliferation, which is 50nsec, 150nsec, for the performance analysis of STTC (Space-Time Trellis Code) using time-space code method which is appropriate for MIMO channel, and performance, in the case, where presumed channel value from long training column section is applied to the according frame in a single frame. The result shows that BER brought SNR improvement of 1.0dB in
본 논문은 무선 멀티미디어용 OFDM 시스템에 적용 할 수 있는 송신다이버시티 기술로 전송 효율 및 수신성능을 최대로 하기 위한 방안을 제시한다. 제안된 방법은 MIMO 채널에 적합한 시공간 부호기법으로 STTC(Space-Time Trellis Code)의 성능 분석을 위해 두 가지의 rms 지연확산, 즉 50 nsec, 150 nsec를 고려한 채널 추정에서 시평균을 위한 파라미터
