Capacity Of MIMO System With Optimally Ordered Successive Interference Cancellation



In wireless communications, spectrum is a scarce resource and hence imposes a high cost on the high data rate transmission. It has been demonstrated that multiple antenna system provides very promising gain in capacity without increasing the use of spectrum, reliability, throughput, power consumption and less sensitivity to fading, hence leading to a breakthrough in the data rate of wireless communication systems The vertical Bell labs layered space-time (V-BLAST) system is a multi-input multi-output (MIMO) system designed to achieve good multiplexing gain.. In this paper, we study the V-BLAST MIMO system architecture, with optimally ordered successive interference cancellation (SIC) receiver in ZERO FORCING EQUALIZATION (ZF) and simulate this structure in Rayleigh fading channel. Based on bit error rate, we show the performance of this receiver, indicates that the ordered SIC detector most effectively balances the accuracy of symbol detection. SIC receiver based on ZF combined with symbol cancellation and optimal ordering improves the performance with lower complexity. Finally, the paper addresses the current questions regarding the integration of MIMO system in practical wireless systems and standards.
