An advanced detection technique in MIMO-PSK wireless communication systems using MMSE-SIC detection over a Rayleigh fading channel

摘要

Efficient signal detection at the receiving end of multi antenna wireless communication is a major challenge in presence of channel fading, interference & noise phenomena. Combination of multiple input multiple output (MIMO) with phase shift keying (PSK) termed as (MIMO-PSK) modulation achieves significant transmission capacity and link quality through spatial diversity and multiplexing. This paper mainly focuses on detection algorithms and by incorporating well-known minimum mean square error successive interference cancellation (MMSE-SIC), proposes an advanced MMSE-SIC detection technique. Via a series of MATLAB simulations it is demonstrated that the proposed detection technique outperforms the conventional zero forcing, MMSE and even that of maximum likelihood detections by further reducing bit error rate without adding substantial system complexity.
