In this paper, we have evaluated the channel capacity of SISO and MIMO system with respect to Rayleigh fading channel. We have compared the results with respect to different receiver diversity techniques like MRC, EGC, SC. We have presented the results of SER v/s SNR with respect to 16-QAM modulation technique. We have also presented the results of SNR v/s capacity of SISO and MIMO system. For simulation, we have used MATLAB R2014 software.

Simulation Results

As multi-antenna being used in MIMO system to transmit signals with the same carrier frequency, one physical channel will contain multi-virtual independent Rayleigh fading channel (VIRFC), among which very small relative time delay is existed, so the definition in MIMO theory for the independent Rayleigh fading channel (IRFC) in MIMO system is wrong. Based on the Shannon formula and the principle of phase-controlled antenna array, an SHPCA system would be presented in the paper to substitute the MIMO system, as well as the 3-dimensional channel capacity formula with its capacity proportional to the number of antennas and that of space division multiplex (SDM), which would have higher efficiency than Shannon formula. Also the principle and research method to obtain the gain of channel capacity would be given in the paper, so as the simulation results.
