MIMO Transceiver Scheme Based on Singular Linear Transform

Multiple input multiple output (MIMO) wireless systems have gained increasing attention today. Based on research for the known spatial multiplexing detection algorithms, in order to improve BER performance and decrease the computational complexity, we propose a MIMO transceiver scheme using singular linear transformation (SLT) in this paper. In this scheme, the transmitted signal vectors with a proper time interval are combined together by an optimizing singular linear matrix. The signal detection at the receiver includes the coarse estimator based on zero forcing (ZF) filter and the fine estimator based on parallel interference cancelation (PIC). Simulation results show that this novel MIMO scheme can improve the receive diversity order, improve the Bit Error Rate (BER) performance, and decrease the computational complexity without loss in spectrum efficiency.
