说明：  认知超宽带的系统设计方面的文章，在权威刊物IEEE上发表的文章，对CUWB有研究的学者有巨大帮助(Cognitive UWB system design aspects of an article published in IEEE which is an authoritative publication.It would bring the tremendous assistance to the related researchers.)

carima模型程序，适合GPC。希望度需要的人有帮助。(carima model program, for of GPC. Hope degrees who need help.)

有借鉴意义哦，BP神经网络的整个训练过程,空间目标识别，采用PM算法。( There are reference Oh, The entire training process BP neural network, Space target recognition algorithm using PM.)

1. 程序中Turbo译码采用了MAP,LOG-MAP，和MAX-LOG-MAP三种算法。 2. 以xxx开头的四个mat文件是四种给定的Turbo码在译码时用到的参数，保存下来的目的是 加快仿真的速度，如果你所仿真的Turbo码不是程序中列出的任意一种，你可以通过函数 trellis来生成自己的相关参数。 3. 程序支持1/2和1/3两种码率的Turbo码，其中1/2码率的Turbo码通过矩阵[1 0 0 1]打 孔得到。在译码时通过对打孔位置添0恢复成1/3码率的码字。 4. 程序中的信噪比表示Eb/N0，通过此参数求得N0，对发送信号进行加噪。(1 program in Turbo decoding using the MAP, the LOG-MAP, and three kinds of the MAX-LOG-MAP algorithm.)

能将频带分解为几个不同频率的信号，可以帮助程序员在做小波变换时使用(Band decomposition can be for several different frequency signal，Can help programmers to use when doing wavelet transform)

Get reduce the size of an original sound file between half to three quarters of the initial size. The FLAC format is often used to sell music online, and as an alternative to MP3 to share when you want to reduce the file size would have

when SNR is high , 1st sample estimator provides good estimate of A. it has no noise effect . so we don’t need averaging effect to reduce noise when SNR is high. However variance is still low in sample mean estimator which shows that in reality ,sample mean is good estimator than 1st sample estimator. So, for high SNR, we do not need to reduce the effect of noise by averaging. or we can say that for high SNR let say >1000 , 1st sample estimator got reduced noise. But as for as variance is concerned , the sample mean has low variance for high SNR as well.
