说明：  包括直接序列扩频CDMA的调制和解调函数(Including direct sequence spread spectrum CDMA modulation and demodulation function)

DC MOTOR CONTROL PID USING MATLAB and SIMULINK

说明：  这是CA码的捕获过程仿真，这能帮助我们更好的理解CA的捕获(This is the CA code capture process simulation, which can help us a better understanding of the capture of the CA)

This set of scripts allows the shadowing of a building to be simulated. It allows the interference between two systems operating at the same frequency to be studied. This simulation can do two main types of simulations: 1. Animated simulation where we have a fixed system, with one or more transmitters, and a single mobile interfering user. The shadowing for the mobile user and the interference it generates can be studied. The animations store each frame as a JPG file, which can be imported in to a video editing package to be converted to a movie. 2. Interference between two systems at the same frequency, each with multiple transmitters

matlab中十进制转化为二进制，程序运行良好，通过测试均正确(matlab decimal to binary conversion, the program runs well, pass the test are correct)

卡尔曼 滤波 去除噪声 测定俯仰角 方位角 距离 等等(kalman filter)

说明：  实现多通道后滤波技术，即经典的ZK算法，支持两路以上麦克风阵列的通道。(After the implementation of multi-channel filtering technique. Absolute classic.)

主要是通过matlab编写设计一个矩形窗的程序(Written mainly by matlab program to design a rectangular window)

针对当前存在的大量数值型数据，将连续型数据离散化，有利于计算机直接处理变量。(In view of the existence of a large number of numerical data, the discretization of continuous data is conducive to deal directly with the variable computer.)

说明：  用MatlaB编程实现GMSK在移动通信系统中的调制解调(Programming with MatlaB GMSK mobile communication system in the modulation and demodulation)
