Matlab平台下仿真实现2*2, 4*4， 6*6天线Alamouti空时编码的MIMO系统，画出不同信噪比下的性能曲线对比。(2* 2, 4* 4, 6* 6 antenna Alamouti space-time coding MIMO system Matlab simulation platform, draw the comparison of different signal-to-noise ratio performance curve.)

This thesis presents simulation data on array operation in wideband communication systems. It is shown that array structures with closer inter-element spacing outperform structures with much larger inter-element spacing. It is also shown that circular structures outperform linear structures. This performance dierence between the classications of arrays is due largely to the circular array s ability to handle high levels of interference. Even though a diversity combining scheme (MRC) was used in the simulator, the arrays provided interference rejection capabilities due to the closely spaced antenna elements.
