说明：  QPSK调制的Matlab程序。包含了QPSK调制及误码率分析。可以调制一随机产生的序列来分析误码率，也可以调制一幅图像来分析误码率。(QPSK modulation of the Matlab program. Contains a QPSK modulation and BER analysis. Can be modulated to a randomly generated sequence analysis of BER, an image can also be prepared to analyze the error rate.)

Single phase A.C. voltage controller using matlab simulink

DPSK信号的调制解调Matlab代码实现的一个例子(采用正交调制解调)，方法简单可靠，使用性强(DPSK signal modulation and demodulation of a Matlab example code (using quadrature modulation and demodulation), a simple and reliable methods, the use of strong)

应用很广泛的卡尔曼滤波标准matlab程序，简单明了，适合初学者。(A wide range of standard Kalman filter matlab program, plain and simple, suitable for beginners.)

说明：  复化simpson公式求二重积分的matlab程序，对于无振荡函数的二重积分效果很好！(Minute of Double Integral formula for the Matlab procedures, without oscillation function for the Double Integral good results!)

网格划分程序，详细讲述了圆形的等边三角形划分，正方形的均等划分(Meshing program, a detailed account of the equilateral triangle divided circular, square equal division)

利用卡尔曼滤波对观测数据进行优化处理，并在观测数据的基础上对卡尔曼滤波进行改进(The Kalman filter is used to optimize the observed data, and the Kalman filter is improved on the basis of the observed data.)

现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFT/DFT,同步(时间/频率同步)和信道估计,以及频率偏移的估计等一系列代码.希望大家能从中得到你需要的东西. (Now I finally found a copy of it to the form of FUNCTION, reproduces OFDM mapping, IDFT/DFT, synchronized (time/frequency synchronization), and channel estimation, as well as the frequency deviation of the estimated range of the code. I hope that everyone will be you need.)
