matlab版本的数字信号处理，适合初学的人。(matlab version of the digital signal processing, suitable for beginners person.)

这是一本关于matlab在数字信号处理上的应用的书，内容完善，希望对大家有用！(This is a book on digital signal processing matlab in the application of the book, the contents of sound, in the hope that useful to everybody!)

this for 16QAM with AWGN and BERR

简要的Gauss列主元消去法，很实用，用matlab实现，还有一个图例，程序说明很详细(brief Gauss main-element elimination, very practical, using Matlab to achieve, there is a legend, a very detailed description of the procedures)
