“基于MATLAB的系统分析与设计—信号处理”一书是一本极好的的书，对初学信号处理的非常值得一读。该书针对应用广泛的的号处理领域，简要介绍了信号处理的基本概念和基本方法，详细介绍了由MATLAB提供的信号处理工具箱函数的用法指南，最后以大量的应用示例，说明MATLAB进行信号处理系统分析与设计方法。( Based on MATLAB-Analysis and Design- Signal Processing, a book is an excellent book, for beginner signal processing is very worth reading. The book aimed at a wide range of applications to deal with the No. field, briefly introduced the basic concepts of signal processing and basic methods, detailed information provided by the MATLAB Signal Processing Toolbox function usage guide, and finally to a large number of application examples MATLAB signal dealing with system analysis and design methods.)

说明：  大小写转换的MATLAB程序。希望对大家有帮助。(Sensitive procedures for the conversion of MATLAB. We want to help.)

In this code, the BER performance of a system which uses sparse channel estimation is compared with a system which uses LSE channel estimation. It is shown that using sparse technique improves the performance of the system
