高斯信道下QPSK仿真程序，显示了QPSK在高斯信道下误码率和信噪比的关系。(Gaussian channel under QPSK simulation program shows the relationship between QPSK Gaussian channel BER and SNR.)

QPSK 仿真 根据原理给出QPSK调制以及解调的SIMULINK仿真图（已调信号波形，解调后的信号波形，眼图和误码率图） 用MATLAB语言实现QPSK调制和解调，给出信号的波形，眼图及误码率等。 (qpsk)

本程序是卡尔曼滤波的源程序包。内含卡尔曼滤波的常用matlab代码(This procedure is Kalman filtering of the source package. Contains the usual Kalman filter matlab code)

Saving Matlab variables to R toolbox Format. Useful for R users.

以3*3为模板在一幅灰度图像中寻找像素值大于给定阈值的所有点(To 3* 3 as the template to look at a gray image pixel value is greater than a given threshold for all points)

基于投影逼近子空间（PASTD）算法的DOA估计，PASTD算法可以快速度估计协方差矩阵的特征向量(doa estimation using pastd algorithm，pastd algorithm can estimate eigenvectors of covariance matrix quickly)

联合对角化方法，用于对多个矩阵同时进行联合对角化，主要用处是盲源分离。(joint diagonalization method for the same time on a number of joint matrix diagonalization, the main use is Blind Source Separation.)

说明：  Brownian Motion, Option.

Modern wireless device have sleep mode which greatly reduce the duty cycle of the power supply.Consider the effect of different duty cycles and transmit times to see the wide range of battery lifetimes one may expect before recharging. results is being plotted of battery lifetime as a function of the duty cycles & duration of the wake up mode.

Plan separator: the code separate the bit 0 to 7 plans of an eight bits image. This is to allow image analysis and to know the most useful part of the image among its features.
