一本介绍matlab学习的书籍，清华出版 高清，非常有用(An introduction to the MATLAB learning books, Tsinghua publishing HD, very useful )

SIMULATION KEYBOARD INPUT

产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2； 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50 ，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列） 改用HDB3码，画出前20个符号对应的波形 改用密勒码，画出前20个符号对应的波形 分别对上述1000个符号的波形进行功率谱估计，画出功率谱 改变信源“0”的概率，观察AMI码的功率谱变化情况(A length of 1000 random binary sequence, and " 0" with a probability of 0.8, " 1" with a probability of 0.2 the AMI code above zero, the pulse width of the symbol width of 50 , the waveform sampling rate Symbol rate 8 times, draw the top 20 of the waveform corresponding to the symbol (the first 20 and gives the source sequence) switch HDB3 code, the first 20 to draw a waveform corresponding to the symbol to switch Miller code, the first 20 symbols correspond to draw The waveforms of the symbol of the waveform 1000 power spectrum estimation, shown to change the source power spectrum " 0" , the probability of observation of the power spectrum of AMI code changes)

信道化软件无线电技术不仅能同时发射整个处理带宽内所有信道上的信号，而且具有很高的计算效率，实时处理能力强，结构简单，可实现性强。这种信道化发射机与信道化接收机一样也是基于多相滤波器来实现的。(Channelized software radio technology can not only transmit signals on all channels in the whole processing bandwidth at the same time, but also has high computational efficiency, strong real-time processing ability, simple structure and strong realizability. The channelized transmitter is also implemented based on polyphase filter as channelized receiver.)

information.m用来计算两个一维向量x和y的互信息。把压缩包中两个程序放在一起就可以运行(information.m used to calculate the two one-dimensional vectors x and y of the mutual information. The compressed package of two programs can run together)

MATLAB PID控制程序包，里面有较强的功能实现。(MATLAB PID control package, which has strong functions.)

说明：  使用matlab有关am调制的仿真编程，基本的仿真代码(Am prepared to use the simulation on matlab programming, the basic simulation code)

这是一个利用matlab求解光波导折射率与其波导深度的模拟程序，利用的是wkb法(This is a use of Matlab for its optical waveguide refractive index waveguide depth simulation program, wkb use of the law)

非常方便的读写固定列宽的时间日期数据，读文件与存文件都是文本格式(Very convenient to read and write fixed column width of the time and date data, read the file and save files are text format)
