多径合成采用可选EG/MR/MMSE合成
信道可选白噪声信道AWGN和IEEE80.215.3a UWB标准信道模型(CM1-CM4)但为了简化，
这里采用了IEEE80.215.3a给出了信道模型中的仿真数据包(如果你是作超宽带的，信道模型程序和数据可从IEEE80.215.3a网站获取)
和大部分仿真一样，模型中的Eb/No指的是单比特信息符号携带的能量和噪声的比例，监督的讲，在AWGN信道中，Eb/No为4.31db时,误码率0.01

Description: This script runs a simulation loop for either a linear or a DFE equalizer. It
uses the RLS algorithm to initially set the weights, then uses LMS thereafter to minimize execution time. It plots the equalized signal spectrum, then generates and plots BER results over a range of Eb/No values. It also fits a curve to the simulated BER points, and plots the burst error performance of the linear and DFE equalizers. The adaptive equalizer objects automatically retain their state between invocations of their \"equalize\" method.
