维特比译码的Matlab程序，摘自短波无线电台项目(Viterbi decoding of the Matlab program)

说明：  用MATLAB生成bpsk信号，并通过AWGN信道的仿真(MATLAB bpsk signal generation, and through the AWGN channel simulation)

超短波及L波段航空信道通信模型，分为停放、滑行、起降及飞行场景，受载频、飞行速率、时延、数据率及波束到达角影响。(Aeronautical channel model of VHF and L band, which is classified into parking, taxi, take-off and arrival, and en-route scenarios, and is affedted by the carrier frequency, velocity, delay, data rate and arrival angle of the beams.)

用于matlab的lrm算法，一个不错的例子(an example of LRM algorithm)

说明：  自从发表《RS纠错编码原理及其实现方法》以来，收到很多初识RS编码的读者的来信， 大家纷纷表示这篇文章对初学者很有帮助，但同时也指出了很多不足。比如第一版的例子中都是按照码长 ， 但在实际应用中并不总是这种情况，还有就是MATLAB程序，由于作者在工程中是在DSP上用C实现的， 所以文章中的MATLAB程序只是用来说明问题，并没有经过调试。做事应该有始有终，这次修改， 附有详细的经过调试的MATLAB程序。并尽量做到程序具有通用性。(Since the publication of RS error-correcting coding theory and method, since the RS coding acquaintance received a lot of letters from readers, we have expressed this article helpful to beginners, but it also points out the many deficiencies. For example, the case of the first edition are in accordance with the code length, but in practical applications is not always such a situation, there is a MATLAB program, because the author works in the DSP using C to achieve, so the article in MATLAB program is used to describe the problem and not debug. Things should stay the course, this changes with the detailed procedures after debugging MATLAB. And as far as possible the procedures are inter-operable.)

说明：  数字通信中的平方根Nyquist滤波器设计，含说明文件和matlab仿真代码(The square root Nyquist digital communication filter design, including documentation and matlab simulation code)
