数据回归计算logistic_regression(Data regression calculation logistic_regression)

信号在信道进行传输时，经常会出现串扰，采用基于最大似然序列估计（MLSE）的电子色散均衡器的方法，克服光纤通信中的由各种色散引起的码间干扰。 研究基于最大似然序列估计（MLSE）的均衡器，采用维特比算法实现，用matlab仿真出采用MLSE后的性能指标（眼图和误码率）的提升。 (Signal transmission channel often occur crosstalk, based on the maximum likelihood sequence estimation (MLSE) electronic dispersion equalizer of the ways to overcome optical fiber communications in a variety of dispersion caused by the inter-symbol interference. Research based on the maximum likelihood sequence estimation (MLSE) of the equalizer, the Viterbi algorithm, a simulation using matlab after using MLSE performance indicators (eye diagram and bit error rate) of the upgrade.)

求取信号的包络，信号的包络含有重要的调制信息，本程序给出了求取信号包络的方法(To strike a signal envelope, signal modulation envelope contains important information, this program gives way to strike a signal envelope)

matlab的一个c4.5实现小程序，（非原创）注意将其中的break改成return，还有一些小瑕疵。(matlab c4.5 applet attention to break into the return, there are some small flaws.)

一本经典的关于光子晶体的书，由John于1987年编写，是学习光子晶体的人不可错过的好书(A classic book on photonic crystals, prepared by the John in 1987, is the study of photonic crystals books were not to be missed)
