Bartlett法：Bartlett平均周期图的方法是将N点的有限长序列x(n)分段求周期图再平均。(Bartlett Law: Bartlett average periodogram method is limited to N-point long sequence x (n) Sub-seeking re-periodogram average.)

基于matlab平台实现,MIT人工智能实验室的目标识别的源码,单径或多径瑞利衰落信道仿真。( Based on matlab platform, MIT Artificial Intelligence Laboratory identification of the target source, Single path or multipath Rayleigh fading channel simulation.)

this is some basic matlab programs.

Low density parity check matrix(Description A program written for generating LDPC matrix in the as pattern as discussed in the research paper , " Time varying periodic convolutional codes with low density parity check matrix" by Alberto jiménez Felströ m and Kamil Sh. zigangirov IEEE Transaction on information theory vol 45 no 6 sept 1999. pages 2181-2191)

该文件使用FIR滤波器滤除采集的心电信号中的工频干扰，实测滤波效果不错，不过并不能处理基线漂移。文件中提供了滤波器的定点系数。(The file uses the FIR filter to remove the collected ECG frequency interference, measured the filtering effect is good, but does not deal with the baseline drift. Document provides a fixed filter coefficients.)
