EMfor_neural_networks
In this demo, I use the EM algorithm with a Rauch-Tung-Striebel smoother and an M step, which I ve recently derived, to train a two-layer perceptron, so as to classify medical data (kindly provided by Steve Roberts and Will Penny from EE, Imperial College). The data and simulations are described in: Nando de Freitas, Mahesan Niranjan and Andrew Gee Nonlinear State Space Estimation with Neural Networks and the EM algorithm After downloading the file, type "tar -xf EMdemo.tar" to uncompress it. This creates the directory EMdemo containing the required m files. Go to this directory, load matlab5 and type "EMtremor". The figures will then show you the simulation results, including ROC curves, likelihood plots, decision boundaries with error bars, etc. WARNING: Do make sure that you monitor the log-likelihood and check that it is increasing. Due to numerical errors, it might show glitches for some data sets.

doppler-autocorrelation
这里有几篇有关doppler frequency offset估计问题的相关文献,主要采用的是信道响应法,自相关法,循环前缀法来估计多普勒频移的。(
Here are a few questions about the doppler frequency offset estimate of the relevant literature, is mainly used in the channel response, self-correlation method, cyclic prefix to estimate the Doppler frequency shift.)

SPIHT_WAVELET
本文介绍的是一种改进的SPIHT算法,是基于图像编码的小波系数块的,它主要是把四个系数分成一个块,与阈值比较,分出重要与非重要,在进行编码。(This article is a modified SPIHT algorithm is based on the wavelet coefficients of image coding block, it is mainly divided into the four coefficients of a block, compared with the threshold value, separate the important and non important, during the encoding.)
