modulation

一种matlab的重要支撑软件，适用于学习 研究的功效。(An important support software matlab, applicable to the study of the efficacy of learning.)

信号用m序列进行扩频，成型滤波和BPSK调制后经过信道发送到接收端，接收端进行解扩解调(Using m sequence spread spectrum signal, after forming filter and BPSK modulation channel is sent to the receiver, the receiver to enlarge demodulation )

实现扩频里随机信号和伪码序列的产生，以及关于生成扩频序列的MATLAB程序，并用载波信号实现2PSK调制,在接收端用非相干积分实现捕获以及虚警概率的计算(Spread spectrum signal generated in the realization and pseudo random code sequence, and generate MATLAB program about spreading sequences and achieve 2PSK modulated carrier signal used to calculate the receiving end with a non-coherent integration to achieve capture and probability of false alarm)

说明：  多种方法实现路径规划，包括遗传算法（GA）、动态窗口、RRT等(path planning with multiple methods)

语音信号的几种概率密度函数，包括高斯模型、Laplace模型和广义高斯模型。(Several probability density function of the speech signal, including the Gaussian model, the Laplace model and the generalized Gaussian model.)

MATLAB在作图应用中的若干问题，一个ppt，哈工大的刘正君老师讲的(MATLAB mapping applications, a ppt, HIT Liu Zhengjun teacher talks)

MM1 code ..please check this out. This is MM1 tandem code that I used recently. May need to modify a bit to your situation. Ok have fun and enjoy!!!!

在mit心电数据库下载的txt格式的心电信号(In the MIT ecg download a database of ecg signals the TXT format )

使用遗传算法对pid进行优化，m文件调用模型文件，直接出结果(Using genetic algorithm to optimize PID, m file calls model files, directly results.)
