SMI方向图和性能(波束形成算法，自己修改） 优点： 收敛速度快 缺点：1 当阵元输出含有较强的期望信时，或者期望信号与干扰信号相关时，性能急剧下降.2 由于权向量含有方向矢量，因此对阵列的幅相差非常敏感；3 ,期望信号的功率不能过大，比干扰信号相差几十dB，也就是说，在小期望信号、大干扰信号情况下，也可进行SMI处理。 (SMI pattern and performance (beamforming algorithm, make changes to) Advantages: fast convergence Disadvantages: 1 output when the array elements with strong expectations of the letter, or related to the desired signal and interference signals, the performance sharply .2 direction vector containing the weight vector, so the array is very sensitive to the amplitude difference 3, the desired signal The power can not be too large, than the difference between the scores of interference signal dB, that is, in the small desired signal, large signal interference case, SMI can also be handled. )

td-scdma链路仿真中的qpsk调制仿真程序，有详细的解释。(td-scdma Link Simulation qpsk modulation simulation program, a detailed explanation.)

因而本文基于MATLAB 针对Nakagami 衰落信道仿真了它的统计 特性,包括接收信号的复包络模拟和在具有最大比合并分集下的电平通过率及平均衰落持续时间的性能分析。重点在于理解和建立采用 MATLAB 进行信道信真的方法及对Nakagami 衰落信道本身统计特性的理解。(Based on MATLAB which Nakagami fading channel simulation for its statistical properties, including the received signal complex envelope simulation and has the maximum ratio combining diversity under the level crossing rate and average fade duration of the performance analysis. Emphasis is on understanding and the establishment of the channel using MATLAB and the letter is really way Nakagami fading channel statistical characteristics of their own understanding.)

说明：  pmvf程序的完整版，鉴于论坛里面所有这个函数都没有完整版的，我究四处找资料补充发一个完整版的吧，里面有 test.m主程序来运行，其他是调用。 Fanger教授PMV－PPD指标计算程序. 欢迎大家互相分享(%PMVF Calculation of the Predicted Mean Vote (pmv) and the % Predicted Percentage of Dissatisfied (ppd) according % Fanger)
