Chapter2

本文件包含了两个直扩和跳频的例子，用MATLAB语言实现，而且还包括例子的原文及大量注释，十分详细(This document contains two examples of DS and FH, with the MATLAB language, but also examples of the original and a lot of notes, very detailed)

说明：  matlab仿真的，功能是实现相关峰值的提取。能够在低信噪比下得到效果较好的相关峰(matlab simulation, feature extraction is to achieve correlation peak. Able to get better low SNR correlation peak)

动态规划的matlab程序，参看胡良剑等编《数学实验--使用MATLAB》P180，所举的例子，希望对初学者有用(matlab dynamic programming)

smooth different is types of filter for DSP in matalb

关于永磁电机的无速度传感器控制，是基于模型参考自适应(it s a mdl project based on matlab.)

说明：  一个新的智能算法Free Search的Matlab源码(A new intelligent algorithm Free Search of the Matlab source)

Geometric Average for some numbers

基于matlab简单图像处理系统中对图片的取反功能(Based on a simple matlab image processing system for the inversion of the image)

bpsk的调制与解调的过程，并采用卷积码，讨论其误码性能随着其功率、频偏、相偏而变化.(bpsk modulation and demodulation process and using convolutional codes, to discuss its error performance with its power, frequency offset, phase offset changes.)
