无线传感器网路中基于地理位置路由算法（即GPSR）在matlab上的仿真(Location-based wireless sensor network routing algorithm (ie, GPSR) simulation in matlab)

这是一个改进阈值函数对LENA图进行去除噪声的处理，效果不错(This is an improved thresholding function of Lena maps deal with the removal of noise, the effect of good)

This folder contains several codes which are about energy detector.

此书是关于数字信号处理的一些算法收集，很详细，全面。(This book is about the digital signal processing algorithms to collect some very detailed and comprehensive.)

说明：  读取SEGY，SU等格式的地震数据、地质雷达数据。最新版本的matlab源文件，在以前版本做了很大的修改，可以读任意时间段或任意CDP段的数据，使用灵活方便。(Read SEGY, SU format, such as seismic data, geological radar data. The latest version of matlab source files, in previous versions to do a lot of changes, can be read any time or any segment of the CDP data, flexible and convenient.)

本程序给出了采用Turbo编码及其信道估计的OFDM的性能仿真。采用时域LS信道估计。对于初学OFDM及信道估计的非常有帮助。(This program is used to simulate the performance of OFDM with turbo coding and time domain LS channel estimation. It is useful for the primer for learning OFDM systems and channel estimation algorithms.)
