IS95中的数据流伪随机序列的产生。用matlab中randn实现(IS95 data streams to be pseudo-random sequence generation. Achieved using randn in matlab)

该算法是经典的信噪比估计算法——误差矢量幅值法，通过计算接收信号中同相分量和正交分量的二、四阶矩，该算法能够很好的估计信号的信噪比(The algorithm is a classic signal to noise ratio estimation algorithm- the error vector magnitude method, by calculating the received signal with the phase component and quadrature component of the second, fourth-order moment, the algorithm can estimate a very good signal to noise ratio)

能够实现四步相移解包裹，对包裹相位能较好的分离出来(unwrap algorithm)

皮肤检测的最终目标是构建一个决策规则，并以此将图像中的像素划分为肤色和非肤色两类，一般通过引入一个衡量像素点颜色与“标准肤色”的距离而实现的，该距离是由相应肤色建模的方法决定的。人脸检测MATLAB源代码关于彩色图像光照补偿(The ultimate goal of skin detection is to build a decision-making rules, and use of the image pixels into skin and non-Fuse types, usually by introducing a measure of pixel color and the " standard color" achieved the distance, the distance The corresponding color from the decision modeling approach. MATLAB source code for face detection on color image light compensation)

These are some code for direct sequence spread spectrum system using different methods which can be used for DSSS signal interception.
