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.)

Fading-channel-simulation
衰落信道仿真
function r = rayleigh( fd, fs, Ns )
r = rayleigh(fd,fs,N)
A Rayleigh fading simulator based on Clarke s Model
Creates a Rayleigh random process with PSD determined
by the vehicle s speed.
INPUTS:
fd = doppler frequency
set fd = v*cos(theta)/lambda
v = velocity (meters per second)
lambda = carrier wavelength (meters)
theta = angle w/ respect to tangent (radians).
fs = sample frequency (Samples per second)
Ns = number of samples of the Rayleigh fading
process to produce
OUTPUTS:
r = row vector containing Ns samples of the Rayleigh
fading process

edgeuser_fr
考虑不同频率复用因子的情况下用户的容量和SINR值变化情况，得出在FRF为3的情况下达到最大的值(calculate the edge user under different frequence reuse factor the performance of capacity and SINR. The result is that when FRF equals to 3 achieve the maximum value.)

pudn_PPS_IHMPT_esti_para
这是基于IHMPT（积分高阶匹配相位变换）方法的多分量三阶相位多项式信号（即立方相位信号）参数估计算法程序包，包含了相关的6个子函数、测试程序以及参考文献等。可以实现对各分量的幅度、各阶相位系数的精确估计。具有广泛的应用，如雷达成像中回波信号具有多阶相位多项式的形式。(This is a matlab code package for an algorithm of estimating parameters of Multicomponent 3-order Polynomial phase signal (Cubic-PPS). The algorithm is based on IHMPT(Integrated High-order Matched Phase Transform). The code package include relevant functions,test codes and reference paper. An accurate estimation of the amplitude and phase coefficients of each order can be obtained by this package. It has a wide application,e.g., the echo signal of radar has the form of PPS.
