Abstract :
This paper reports on the performance of the space time block coded MIMO system with spatial redundancy which is accomplished using a larger than required numbers of antennas. The proposed scheme guides the transmitted power onto the RF branches with higher gain coefficients. The carried out theoretical analysis shows that the scheme can achieve higher channel capacity and lower symbol error rate (SER) than the conventional system with all antenna elements utilized in the transmission process. The simulation results confirm the theory and show that the proposed system is effective in a flat Rayleigh fading environment.
