An Improved Detection and Transmit Multiplexing Scheme for Hybrid STBC in MIMO-OFDM Systems
نویسندگان
چکیده
This paper proposes improved schemes for hybrid STBC systems. The hybrid space-time block codes (STBC) system is a combination of STBC scheme and SM scheme. It is aimed to obtain both diversity gain and spectral efficiency gain. In hybrid STBC, conventional schemes can’t achieve good BER performance of STBC symbols due to interference from other symbols. The proposed scheme improves BER performance by iterative detection scheme. Moreover, it increases the data bit rate effectively with a little performance loss.
