sumlink的ppt，对初学者有用，里面包含了对于sumlink的基本模块的介绍(sumlink the ppt, be useful for beginners, which includes the basic modules for sumlink Introduction)

说明：  Viterbi算法源程序,注释简洁,利于使用(Viterbi algorithm source, concise notes, beneficial use)

This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.

说明：  这个程序属于matlab里面的画图功能，里面包含很多小功能(This process belongs to the drawing inside the matlab function, which contains many small features)

说明：  em算法的一些重要程序，值得下载参考学习(some of the important procedures em algorithm, it is worth to download the reference)

A Cover Tree is a datastructure helpful in calculating the nearest neighbor of points given only a metric.

DBSCAN是一个基于密度的聚类算法。改算法将具有足够高度的区域划分为簇，并可以在带有“噪声”的空间数据库中发现任意形状的聚类。(DBSCAN is a density-based clustering algorithm. Algorithm change will have enough height to the regional cluster. and to be with the "noise" of the spatial database found clusters of arbitrary shape.)
