说明：  这是一个基于Simulink的通信系统的仿真程序，主要内容是QPSK在IS-95前向信道中的应用，以衡量其性能。(This is a simulation-based communications system simulation program, main contents of the QPSK in IS-95 to the channel, in order to measure its performance.)

nonlocal means算法的实现，用于去除斑点噪声(nonlocal means)

针对激光光斑图像或荧光小球等图像进行高斯拟合定位其中心坐标。可同时定位一幅图像中的多个小球。要求对象模型符合高斯分布。(For laser speckle images or small fluorescent balls image gaussian fitting location and its center coordinates. Can be positioning an image of the multiple balls at the same time. Request object model conforms to the gaussian distribution.)

MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)
