EMD 算法，消除信号趋势项，可以作为信号预处理的部分(Part of the EMD algorithm to eliminate the signal trend term, can serve as a signal preprocessing)

本资料涵盖量丰富，关联维，信息量，GP算法，熵等工具箱，并且每种问题采用的方法有好几种，便于比较。其中包含了LORENZ的一些算法。积累了本人一段时间的整理成果。(This information covers the amount of rich, correlation dimension, the amount of information, GP algorithm, entropy and so the toolbox, and the methods used for each question there are several, to facilitate comparison. Which contains a number of algorithms LORENZ. I have accumulated the collation of the results for some time.)

关于雷达参数估计的一个范例，内容比较具体(About the radar parameters estimated an example, more specific)

It should be noted that there is still room to improve the speed and the memory usage of the algorithms, using for instance displacement structure algorithms for the RQ decomposition and Lanczos algorithms for the SVD.

turbo码的编解码程序，采用max-log-map算法，简单易用。程序采用QPSK调制，信道为AWGN(turbo code decoding process, using max-log-map algorithm, easy to use. Program uses QPSK modulation, AWGN channel is)
