使用MATLAB仿真，产生矩形脉冲，是超宽带传输信号的基本图形 (Simulation using MATLAB, resulting in the rectangular pulse, ultra-wideband transmission signal is the basic graphics)

说明：  用newton迭代法求方程根的源代码 给出了newton迭代法的实现(with chemotherapy iterative method for equation of the source code is given to the Newton iterative method to achieve)

说明：  PCA-SIFT算法的实现，PCA-SIFT是对SIFT算法的改进，用PCA替代SIFT算法中的第四步，提高了效率，且准确率更高(PCA-SIFT algorithm implementation, PCA-SIFT SIFT algorithm is an improved SIFT algorithm with PCA instead of the fourth step, improve efficiency, and higher accuracy)

当前的很多海洋数据都是海量数据，传统的ftp下载费时费磁盘，因此，openDAP方式越来越多，通过opendap可以选择直接需要的时间、空间范围内的资料。nctoolbox结合matlab实用，效果非常好的opendap工具包(NCTOOLBOX- 20130305 Full instructions and documentation at: http://code.google.com/p/nctoolbox/ We are in the progress of moving the project hosting here to github.com. Brief summary: *Prequisites *Matlab R2008a+. You can verify the version of Matlab by typing: version *Java 6+. You can verify the version of Java used by Matlab by typing: version( -java ). *The version returned should start with Java 1.6 . If it starts with Java 1.5 you can try updating the Matlab JVM: http://www.mathworks.com/support/solutions/en/data/1-1812J/ or use the older nctoolbox-20091112 version of this toolbox. )

定时恢复在接收机中是必不可少的环节，只有定时恢复环节性能良好才能正确解调出信号。 位同步-gardner算法(Timing recovery is an essential part of the receiver, and the signal is demodulated correctly only when the timing recovery is in good performance.)

it describes about the Bwt transform for image

说明：  采用一种量子粒子群算法来对RBF网络进行优化(Using a quantum particle swarm algorithm to optimize the RBF network)
