ContrastStretchNorm
Stretches contrast on the image and normalize image from 0 to 1. The main difference of this function to the standard stretching functions is that standard function finds global minimum and maximum on the image, then uses some low and high threshold values to normalize image (values below LowTHR are equated to LowTHR and values above HighTHR are equated to HighTHR)

Filtro-3-vias
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： 因为经典粗糙集只能处理离散型数据，而连续性数据必须离散化才能处理，但是离散化可能会丢失部分重要信息，所有使用基于邻域粗糙集的属性约简去处理连续性数据。(Attribute reduction based on neighborhood rough set)

Digitallightsignaltransmissioncodedesign
为了匹配信道特性达到较佳的传输效果，应选用适当码型，以便在最小传输带宽的条件下大大减小或消除这种干扰。选用了MATLAB软件进行了仿真，设计实现了一些简单的常用码型(In order to match the channel transmission characteristics to achieve better results, should use the appropriate code type, so that under the conditions of minimum transmission bandwidth substantially reduce or eliminate such interference. Use of the MATLAB simulation software, designed and implemented some simple common pattern)
