FSK
数字频带通信系统
输入:首先输入模拟信号,给出此模拟信号的时域波形。
数字化:将模拟信号进行数字化,得到数字信号,可以选择PCM编码。
调制:可以选择简单的二进制数字调制方式。例如振幅键控(2ASK)、相移监控(2PSK)、频移键控(2FSK)、差分相移键控(DPSK)等。要求每个题目至少选择两种调制方式。有能力的同学也可以选择其它高效的调制方式?例如多进制数字振幅键控等?给出调制后信号的时域波形。
信道:假定信道属于加性高斯信道?或自行设计。
解调:相应的2ASK、2PSK、2FSK、DPSK解调,仿真获得解调输出波形。
PCM解码:给出解码后的模拟信号的时域波形,并与输入信号进行比较。
系统性能分析:比较在不同调制方式下,该数字频带传输系统的性能指标,即该系统的输出误码率随输入信噪比的变化曲线。(Digital frequency band communication system)

fit_ML_maxwell
fit_ML_normal - Maximum Likelihood fit of the log-normal distribution of i.i.d. samples!.
Given the samples of a log-normal distribution, the PDF parameter is found
fits data to the probability of the form:
p(x) = sqrt(1/(2*pi))/(s*x)*exp(- (log(x-m)^2)/(2*s^2))
with parameters: m,s
format: result = fit_ML_log_normal( x,hAx )
input: x - vector, samples with log-normal distribution to be parameterized
hAx - handle of an axis, on which the fitted distribution is plotted
if h is given empty, a figure is created.
output: result - structure with the fields
m,s - fitted parameters
CRB_m,CRB_s - Cram?r-Rao Bound for the estimator value
RMS - RMS error of the estimation
type - ML

KNNMeanFilter
说明: 原理:以待处理的像素作为中心,取一个nXn的模板,在模板中选择k个与待处理像素的值最接近的像素,将这k个像素的均值替换原来的像素值。
假设n=3,k=5,调用方法:b = KNNMeanFilter(a, 3, 5)(Principle: to be treated as the center pixel, take a nXn template select the template and the pending k-nearest pixel values of pixels, this k pixels mean replacing the original pixel value. Assuming n = 3, k = 5, call the method: b = KNNMeanFilter (a, 3, 5))
