Abstract(in English) | In this paper, we propose a combined minimum mean square error (MMSE) and maximum likelihood (ML) multiuser detection scheme for space-time block coded orthogonal frequency division multiplexing (STBC-OFDM) which has improved performance but with low complexity. In particular, we propose a reduced complexity ML post-detection (ML-PDP) scheme which can correct erroneously estimated bits from the outputs of MMSE multiuser detection. The proposed ML-PDP scheme performs sequential search to detect a predefined number of bits with higher probability of error and then uses ML detection to correct them. Upon controlling the number of corrected bits it is possible to balance the system performance with complexity associated with the ML-PDP. We show that significantly improved performance can be achieved over MMSE-MUD at the cots of only a small additional complexity. |
