案例源代码实现，用matlab实现定时器的编程代码。(Case source code, using matlab realize the timer programming code.)

matlab在数学建模中的一些有用例子,希望对大家有所帮助.(matlab in the mathematical modeling of some useful examples, and they hope to be helpful to everyone.)

小波去噪 用了几种不同的方式进行限制，有软域值，硬域值还有新开发的一种方式(wavelet)

用Matlab语言实现基于小波DWT域水印技术(Matlab language using DWT domain watermarking technique based on wavelet)

主要实现的是2*2用户，采用qpsk调制，实现仿真模拟图(The main achievement of 2* 2 users, qpsk modulation, simulation Figure)

The book gives the instruction of using Multisim 9 for educators

说明：  用MATLAB/SImulink 搭建的单相光伏并网逆变器仿真(Single-phase photovoltaic grid-connected inverter simulation with MATLAB/SImulink)

A Costas loop is a phase-locked loop used for carrier phase recovery from suppressed-carrier modulation signals, such as from double-sideband suppressed carrier signals. It was invented by John P. Costas at General Electric in the 1950s. Its invention was described as having had "a profound effect on modern digital communications".
