用于信道均衡的RLS算法，可用于水声信道的改进算法(RLS algorithm for channel equalization, the improved algorithm can be used for underwater acoustic channel)

复旦大学自动控制理论ppt第1章,关于matlab的概述(Fudan University, Automatic Control Theory Chapter 1 ppt, an overview on matlab)

This book includes nine examples that represent typical design tasks of an automotive engineer. It shows how The MathWorks modeling and simulation tools, Simulink® and Stateflow,TM facilitate the design of automotive control systems. Each example explains the principles of the physical situation, and presents the equations that represent the system. The examples show how to proceed from the physical equations to the Simulink block diagram. Once the Simulink model has been completed, we run the simulation, analyze the results, and draw conclusions from the study.

混沌粒子群算法。将混沌搜索方法，用在粒子群算法中，避免了粒子群的陷入极小值的缺点。(Chaotic particle swarm algorithm. The chaos search method, use on the particle swarm algorithm, avoid the particle swarm into the minimum faults.)

HV non compesated line program

周期信号有效值算法，取半周期进行计算，采用matlab s函数编写(Periodic signal RMS algorithm, take half cycle is calculated using matlab s function)

说明：  对于matlab的讲述很全的一本书，编程讲的很好(This is a nice book the people who have probelems in matlab programing and learning)

该程序利用三阶科斯塔斯环实现锁相环结构，有效的估计输入信号的相位变化，在通信系统的同步上广泛应用。(The program uses the third-order Costas loop to achieve phase-locked loop structure, effectively estimate the phase change of the input signal, widely used in synchronous communications system.)

跳频图案是跳频通信成功的基础，本代码计算了r=15时的m序列优选对，通过找到m序列的特征相位，模2得到了平衡Gold序列(Frequency hopping patterns is fundamental to the success of frequency-hopping communication, the code calculated the r = 15 when m sequence optimization right, by finding the characteristics of m sequence phase, mode 2 has been balanced Gold sequences)
