  • In multiuser space-time coding system the research already made is almost focused on STTC and STBC scheme. For this reason, a multiuser space-time coding system combined with Turbo-BLAST scheme is proposed. The conventional iterative receiver with Symbol-Level Cancellation (SLC) and detection still has a high computation complexity, so a low complexity iterative receiver scheme with Bit-Level Cancellation (BLC) and detection is proposed which can performs bit-level cancellation by decomposing of an M-QAM constellation into a linear combination of binary constellations. Theoretic analysis and simulation results show that the proposed scheme has a low complexity with no performance degradation compared with conventional iterative receiver, while the high spectral efficiency of the system from BLAST is retained.
