| Abstract(in English) | In multi-carrier code division multiple access(MC-CDMA)systems, delay waves cause inter-code interference and degrade bit error rate(BER)performance as the number of multiplexing users increases. In this paper, we propose a new quasi-maximum likelihood method which jointly performs multiuser detection and error correction decoding for coded MC-CDMA systems to mitigate the inter-code interference. The proposed method uses codewords generated by the ordered statistics decoding for the quasi-maximum likelihood detection. In the proposed method, we only consider the codewords which have relatively high reliability values, where the reliability values are calculated from received signals, so that we can significantly decrease the number of codewords considered in the quasi-maximum likelihood detection. As the result of numerical simulations, we show that the proposed method exhibits better BER performance than a conventional method. |
