this tutorial will help beginners in the radar image processing. The programs are arranged in form of the chapters. all the best.

Constrained optimization has been explained with matlab 2007a. This has been explained with various benchmark functions. The main program can be directly applied to knapsack problem and portfolio optimization problem directly. These programs have been written in a menu driven manner.

天在维普下载了一篇SPIHT算法改进的论文，（耿兴云，《基于改进SPIHT的静态图像编码》，电脑知识与技术：学术交流-2007年5期），我根据该文提出的改进算法，用Matlab来实现，却发现改进算法的程序运行速度比原算法还要慢，希望有兴趣的朋友进来看看，评论一下原因。(Days in the VIP downloaded a SPIHT algorithm to improve the paper, (Gengxing Yun, " based on improved SPIHT still image coding," Computer Knowledge and Technology: 5-year academic exchange-2 007), in accordance with this paper the improved algorithm Matlab to achieve, but found that the improved algorithm runs faster than the original algorithm is also slow, hope to have interested friends come to see, comment on why.)

对采用双二进制信号脉冲的2电平PAM通信系统进行Monte Carlo仿真。输入二进制序列为{bn},预编码序列为{dn},幅度序列为｛an},相关序列为{cn}。将高斯噪声加到接收序列{bk}上去以形成检验信号的输入，并恢复这个数据。对1万个比特执行这个仿真，并在σ2=0.1,0.5,1时分别测量比特差错概率。用此概率跟无ISI的PAM的BER曲线作对比并进行分析。(Partial-Responsing Signal。)
