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