该程序源代码实现了CDMA通信系统性能的仿真，用MATLAB实现了直序、跳时、跳频以及M序列，GOLD序列等的产生，及在AWGN和RAYLEIGH环境下误码率的计算(The program source code to achieve the performance of CDMA communication system simulation, using MATLAB realize the direct sequence, time hopping, frequency hopping and M sequences, GOLD sequence generation, and in the AWGN environment and RAYLEIGH BER calculation)

knn 只是个函数实现 需要其它函数的引用(k-nearest neighbor u need to import this function to other functions to run it)

说明：  Radar 动目标MTI检测器 雷达MTI动目标检测，里面包含所有动目标检测的滤波器，很实用，有不同系数的滤波器进行比较，滤波器可以直接使用(Radar Moving Target MTI Detector Radar MTI moving target detection, which contains all moving target detection filters, is very practical. The filters with different coefficients are compared. The filters can be used directly.)

these program help to understand fading channel and also in exponentail and traingular pdf random number generation

MATLAB_SIMULINK通信系统建模与仿真实例精讲，包含DS_CDMA通信系统、IS95前向链路系统、MIMO通信系统、OFDM通信系统、蓝牙调频通信系统(Matlab Simulink Communications system modeling and Simulation examples succinctly, including DS_CDMA communication system, IS95 forward link systems, MIMO communication systems, OFDM communication system, Bluetooth FM communication system)

This code simulates the peak to noise power ratio of ldpc coded mimo systems

This model shows the implementation of a QPSK transmitter and receiver. The receiver addresses practical issues in wireless communications, e.g. carrier frequency and phase offset, timing offset and frame synchronization. The receiver demodulates the received symbols and outputs a simple message to the MATLAB command line.

the paper describes the existing techniques of face detection.
