The particle swarm optimization algorithm is very popular this years and widely used in many specilities. Our procedure is hoped to bu useful to you. (The particle swarm optimization algorith m is very popular this years and widely used in ma ny specilities. Our procedure is hoped to use negation ful to you.)

ASK Modulation using MATLAB

完整的空间卫星轨道仿真程序以及空间卫星导航仿真程序。(Complete space orbit satellite navigation and space simulation program and simulation program.)

1. BPSK modulation of data which ever you input (default data is “MANIPAL REDDY”). 2. MANIPAL REDDY is changed into ASCII Format and into two-bit format for BPSK Modulation. 3. Chaos is used for spreading the binary bit sequence. 4. Uniformly distributed Noise is added to Spread signal. 5. After reception Chaotic Chip sequence is used to recover message . 6. Filter is used for removing spikes and noise. 7. Note the filter is used is just for showing a little realisitic picture. 8. Appropriate filter should be used. 9. The original data in binary and recovered data in binary format are compared

小波包分析提取振动信号中的特征频率，是路径规划的实用方法，计算多重分形非趋势波动分析。( Wavelet packet analysis to extract vibration signal characteristic frequency, Is a practical method of path planning, Calculate the multifractal trend fluctuation analysis.)

利用小波变换进行图像灰度增强，其中与直方图，中值滤波图像处理进行了对比(Using wavelet transform image gray enhanced, including histograms, median filter image processing were compared)

说明：  GA算法，在MATLAB上的实现，是源程序(GA algorithm, the realization in MATLAB is the source)
