详细的卷积编码与维特比译码算法。产生随机信号，对信号进行卷积编码，然后经过数值转换、格雷编码，QPSK调制，进入加噪信道，之后进行QPSK解调，格雷解码， 数制转换、 维特比译码得到接收端的信号。(Detailed convolutional coding and Viterbi decoding algorithm. Random signal, the signal convolution coding, and then through numeric conversion, Gray coding, QPSK modulation, plus noise into the channel, followed by QPSK demodulation, decoding Gray, number system conversion, Viterbi decoding to get the receiving end of the signal.)

流体力学方法模拟双离子一维鞘层的matlab代码，可作为交流学习使用(Fluid dynamics simulation of one-dimensional dual ion sheath matlab code, can be used as learning to use exchange)

本程序简单地实现了LZ78编码的功能，包括从文件输入以及输出(This program implements the LZ78 encoding simple features, including file input and output from)

<精通MATLAB>根据这本书写的相应的运筹学里的源代码，都是最基本的算法，没有进行改进(<Proficient in MATLAB> According to this writing tacticians in the corresponding source code, are the most basic algorithm, no improvements)

vmd源程序的修改版，看起来没那么费尽，更容易懂。(vmd source of the modified version, does not look so racked and easier to understand.)

COMPARISON OF DIFFERENT MODULATION SCHEMES

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.)
