| Summary: | In this paper, we consider a V-BLAST/STBC wireless
communication architecture, which integrates Alamouti
space-time block codes (STBC) layer with vertical Belllabs
layered space-time (V-BLAST) layer, in MIMO
wireless communication system with four transmitter and
three receiver antennas over Rayleigh flat-fading channel.
We propose an algorithm, which combines the algorithm
of successive interference cancellation zero-forcing (SIC
ZF) and successive interference cancellation zero-forcing
with maximum a posteriori probability (SIC ZF MAP).
The proposed algorithm (SIC ZF / ZF MAP) reduces the
complexity if compared with the algorithm of SIC ZF
MAP alone. Simulation results show the symbol error rate
performance degradation of the proposed algorithm is
small compared to SIC ZF MAP detection. |
