In the recent years MIMO has drawn significant attention of researchers in the field of wireless communication. Multipath fading is major bottleneck in increasing the data rate and reliability of transfer of information over wireless channel. Channel coding Techniques which are used to improve reliability is insufficient to meet the requirements of modern multimedia communications. This paper presents simulation results and comparative analysis of some Spatial Diversity Techniques for Multiple Input Multiple Output (MIMO) based Wireless Communication Systems. Performance of Alamouti scheme and Space Time Block Codes (STBC) are evaluated through MATLAB simulation study. The Bit Error rate and Code rates of the schemes are compared. The simulation is carried out for various modulation schemes.
