Abstract
Performance of the Alamouti algorithm based M-ary $\small{2{\times}N}$ OSTBC(Orthogonal Space Time Block Coded) MIMO(Multi Input Multi Output) system has been simulated varying two main parameters - the number of constellation(M), and the number of receiving antennas(N). Computer simulation has also been carried out using Matlab software for performance comparison between $\small{2{\times}N}$ MIMO and MRC(Maximal Ratio Combining) diversity antenna system to evaluate the degree of enhancement achieved through the use of Alamouti $\small{2{\times}N}$ MIMO. Under 10 dB EbNo QPSK scenario, $\small{2{\times}1}$ MIMO brought 4.2 dB BER improvement over single antenna system and $\small{2{\times}2}$ MIMO resulted in 7.4 dB BER improvement over $\small{1{\times}2}$ MRC.
