parks maclean algorithm for low pass filtering

基于电流滞环比较器的PMSM调速控制，通过对电流的滞环控制，达到控制转矩的目的。控制效果好！(PMSM speed control based on current hysteresis comparator, current hysteresis control, to achieve the purpose of the control torque. Control effect is good!)

适用于matlab用打靶法解决有边界问题的微分方程，各种参数已经在程序中说明清楚了(shooting method)

数字锁相环数学模型,对有研究信号调制的数学建模.(Digital phase-locked loop mathematical model of research has the mathematical modeling of signal modulation.)

自己写的matlab程序，用kay方法进行频率估计，已通过验证。(kay matlab)

This code is useful for multi user mimo systems

程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制； 根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声； 接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。 结果表明10^-3对应大约12->13dB(Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB)

This ia my circle and other programs. They compute the circle and ploit it in matlab.

说明：  求解分形维数，采用功能函数法，很方便，从而很好的对分形几何进行分析(Solving the fractal dimension, function by function, it is convenient to a good analysis of fractal geometry)
