Ex4-22 单射函数问题
&laquo 问题描述:
设函数f将点集S = {0,1,&#61516 , n -1}映射为f (S) = { f (i) | i&Icirc S} &Iacute S 。单射函数问题要
从S中选取最大子集X &Iacute S 使f (X )是单射函数。
例如,当n=7, f (S) = {1,0,0,2,2,3,6} &Iacute S 时, X = {0,1,6} &Iacute S 是所求的最大子集。

This demonstration illustrates the application of adaptive filters to signal separation
using a structure called an adaptive line enhancer (ALE). In adaptive line
enhancement, a measured signal x(n) contains two signals, an unknown signal
of interest v(n), and a nearly-periodic noise signal eta(n). ...

Abstract-The effect of the companding process on QAM signals
has been under investigation for the past several years. The
compander, included in the PCM telephone network to improve
voice performance, has an unusual affect on digital QAM data
signals which are transmitted over the same channel. The ...
