这是关于数字水印的攻击例程！经过调试，可以放心使用！(This is on digital watermarking attacks routines! After debugging, can be assured use!)

演示对称振子天线的立体方向图，此程序为动画效果的程序。(Demo three-dimensional symmetric dipole antenna pattern, the procedure for animation programs.)

基于LMS算法和RLS算法的自适应滤波器设计(Based on LMS and RLS adaptive filter design)

Very simple matlab code for QAM modulation

non-local means filter 用于去噪，里面的矩阵操作编写的代码，速度比较快(non-local means filter for noise removal, inside the matrix manipulation code written faster)

说明：  标准粒子群算法的实现思想基本按照粒子群算法(2)----标准的粒子群算法的讲述实现。主要分为3个函数。第一个函数为粒子群初始化函数(His thought of the implementation of the standard particle swarm algorithm according to the particle swarm algorithm (2)- the standard particle swarm algorithm about implementation. Mainly divided into three functions. The first function of particle swarm initialization function)

对QAM的频谱、散图、眼图以及误码率进行了仿真。使用matlab语言。(QAM spectrum of scattered diagram, eye diagram and BER simulation. Using matlab language.)

Convert grayscale images to RGB using specified colormap.

这是一个非常完整的pi/4dqpsk 调制解调的matlab仿真，给出了各个阶段的波形图，并且分析了在高斯信道下面的误码率，以及星座图和功率谱(This is a very complete matlab simulation of pi/4dqpsk modulation and demodulation. The waveform diagram of each stage is given, and the bit error rate under Gao Si channel, constellation diagram and power spectrum are analyzed.)
