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.

Simulation Results

In this paper, I have presented the performance evaluation of different STBC technique in MIMO Rayleigh fading environment. I have evaluated the BER of SISO, MISO and MIMO technique. I have proved that the lowest value of BER is achieved in STBC technique. I have evaluated the BER of real STBC and complex STBC technique with Rayleigh fading channel. The STBC technique is also reduced the complexity of the receiver. We have also compared the performance of MIMO technique with other techniques like SISO and MISO. The lowest value of BER is achieved in MIMO technique. The STBC technique is exploit the diversity gain by inserting more number of antennas at transmitter side. Simulation results are based on MATLAB software.
