Description: MMse信道估计数，都需要通过导频序列来获取同步信息，而且为了达到更好的均衡效果，OFDM 系统也要进行简单的频域均衡。此外，OFDM与SC．FDE的帧格式也十分相似，都 需要添加CP(SC．FDE采用UW)来吸收前面帧的干扰并满足循环卷积特性。 由于OFDM在结构和原理上都与SC．FDE十分相近，可以设计一种双模式系统。 双模式系统仅仅改变IFFT模块在发送端和接收端的位置就可以同时支持两种系统传 输。两种系统都可以通过编码、自适应调制和空间分集提高性能。而且，

Description: Title: MMSE Receiver for DS-SS in AWGN Channel
Author: Panson Tantikovit
Summary: An adaptive receiver for DS-SS systems
MATLAB Release: R12.1
Required Products: Communications Toolbox,Signal Processing Blockset
Description: This is an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain.

Description: 关于simu1:
在simlink运行之前的初始化过程中，完成了信道时延和幅度的估计，多径合成权系数估计
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
关于zslsimu直接运行simuuwb.m可看到结果)
显然和simu1一样，只是增加了.m文件，修改.m文件中的重要参数:多径数、PN序列长度、PN序列、单个信息码元宽度Tb(单位ns)、每个脉冲宽度Tc(单位ns)、系统的仿真精度Ts(单位ns)、仿真时间
chanidx=1:1是因为考虑信道数据文件太大，不好上传，想得到精确的仿真，同一个信道类型(chantype)，最好仿真100次实现，信道文件可由UWB标准组织下载-on simu1 : simlink operation before the initialization process, completed the channel delay and the magnitude of the estimates, Multi-Path weights estimated Drive synthesis using the optional EG/MR/Synthesis MMSE Channel optional white noise channel AW GN and IEEE80.215.3a UWB channel model (CM1- CM4) in order to simplify IEEE80.215.3a used here is a channel model for the simulation data packets (if you were for extra-wide belt, channel model and data from IEEE80.215.3a website access) and most simulation, Model of Eb/No refers to the single-bit symbols to carry the message of energy and noise ratio, supervision speaking, In AWGN channel, Eb/No for 4.31db, BER 0.01 zslsimu directly on the operation simuuwb.m can see the result) clearly and si mu1, only increased. m document change
