Abstract

Due to the ever increasing requirement of faster data propagation, Multiple Input Multiple Output (MIMO) is an emerging topic in the future generation wireless communications in which spectrum efficiency, network coverage, and link reliability factors can be easily achieved. By combining MIMO and Phase Shift Keying (PSK) modulation, this paper proposes a novel technique termed as MIMO-PSK receiver in order to perform significant improvement in channel capacity in presence of Space-Time Block Coding (STBC) over multipath fading channels. STBC provides full or near full data rate according to its orthogonality principle. Higher order MIMO-PSK receiver configurations are mainly considered for simulating optimal channel performances, i.e. Bit Error Rate (BER) as well channel capacity. From MATLAB simulations, it is clear that optimal channel performance of MIMO-PSK receiver can be obtained with increasing number of antennas as well as higher order PSK modulation.
