衡量一个数字通信系统性能好坏的指标很多，误码率性能就是一个重要的指标。误码率是指错误接收的码元数载传输总码元数中所占的比例。在该章中，我们将通过MATLAB仿真在发送平均功率和传输速率相同的情况下(A digital communication system performance measure indicators of good or bad a lot of bit error rate performance is an important indicator. Bit error rate refers to the number of errors contained in received transmission symbol the number of total yards per share. In this chapter, we will send through MATLAB simulation of average power and transmission rate in the same circumstances)

提出一种新的混合数字水印算法，它利用了 两种方法最好抵制JPEG压缩。(develop a novel hybrid watermarking algorithm that exploits the best of both approaches for greater resilience to JPEG compres- sion. )

包括连续信号以及离散信号的产生与处理 适用于数字信号处理(Including continuous and discrete signals in the signal generation and processing applied to digital signal processing)

这个是我在网上找的关于小波分解和重构的matlab程序(This is my search on the net on wavelet decomposition and reconstruction of matlab program)

并用S函数编制相间距离保护和接地距离保护算法程序,构建相应的保护模块,实现了三段式距离保护。仿真结果表明,所建立的三段式距离保护模型能够正确反映在保护区内的不同类型的短路故障并发出动作信号,使断路器跳闸实现输电线路的保护功能。 (A distance protection simulation model of transmission line was established by using Simulink and SimPowerSystem toolbox inMatlab. S-function was used to programe the distance protection of phase faults and earth faults and the relevantprotectionmodelswere created to build distance protection.The simulation results show that the three-stage distance protectionmodel can respond to allkinds of faultswithin protection zones correctly and send correct signal to the breaker of the line. )

基于FFT的非相关累加捕获伪码，并计算各个信噪比下的检测概率。(FFT-based non-related pseudo-code cumulative capture and calculate the probability of detection under various signal to noise ratio.)

该代码是红外目标粒子滤波跟踪算法，代码可以运行，且效果很好。(The code is infrared target tracking algorithm of particle filter, the code can be run, and the effect is very good. )

基于羽田孜模型的预知的路径损耗 基于爱德华兹和德金模型的路径损失预知 基于帕森斯与伊布拉因模型的路径损耗预知(Tsutomu Hata model based on predictable path loss payments based on Edwards and the German model to predict the path loss model based on Parsons and Ibraim predict the path loss)

说明：  canny边缘检测，还不错，希望能对大家有帮助(canny edge detection, well, hope you can help)

matlab绘图与图形处理技巧。值得参考一下。(matlab graphics and graphics processing skills. Worthy of reference.)
