Channel Ranking based Joint Symbols Detection for MQRD-PCM/MIMO-OFDM AHN, Chang-Jun アン, チャンジュン JEONG, Incheol 安, 昌俊 鄭, 仁哲 copyright©2008 IEICE application/pdf MIMO-OFDM is considered a key technology in emerging high-data rate systems. With MIMO techniques, the transmission quality deteriorates due to co-channel interference (CCI). Several signal detection schemes have been proposed to mitigate this problem. However, it is impractical to use the conventional methods without reducing theirs computational complexity. Previously, we have proposed a parallel detection algorithm using multiple QR decompositions with permuted channel matrix (MQRD-PCM) for MIMO-OFDM to reduce the system complexity. This method achieves a good BER performance with low system complexity. However, since MQRD-PCM is a kind of parallel detection method, the wrong detection probability is increased due to the bad channel SINR of the transmitted signals. To overcome this problem, in this paper, we propose the channel ranking based joint symbols detection for MQRD-PCM/MIMO-OFDM. 第２３回　信号処理シンポジウム　２００８年１１月１２日～１４日（金沢）, 査読有り 電子情報通信学会(IEICE) 2008-11 eng conference paper VoR https://hiroshima-cu.repo.nii.ac.jp/records/1588 http://www.ieice.org/ess/sip/ http://www.ieice.org/ess/sip/ Proceedings of SIP Symposium 310 315 https://hiroshima-cu.repo.nii.ac.jp/record/1588/files/B5-2.pdf application/pdf 795.1 kB 2023-03-02
