This paper proposes an adaptive iteration detection scheme for a combination of STBC and SM scheme in LTE systems. The hybrid space-time block code system is a combination of STBC and SM scheme. It obtains both diversity gain and spectral efficiency gain. The conventional combination of STBC and SM scheme can't achieve good BER performance of STBC symbols due to interference from other symbols. The iterative V-BLAST detection scheme improves BER performance but has complex iterative detection process. The proposed scheme applies the adaptive iterative detection scheme by channel condition and can reduce complexity of LTE systems. LTE systems require high speed. Therefore, this scheme can be applied effectively in LTE systems. [ABSTRACT FROM AUTHOR] |
