Description: 直接序列扩频通信可以有效地抵抗来自信道中的窄带干扰。在一个直扩通信系统中,扩频是通过伪噪声序列(PN)对发送的信息数据进行调制来实现的。在接收端,原伪噪声序列和所收信号的相关运算可将窄带干扰扩展到DS信号的整个频带,使干扰等效为幅度较低频谱较平坦的噪声；同时，将DS信号解扩,恢复原始信息数据。-direct sequence spread spectrum communication can be effective resistance from the channel narrowband interference. In a DSSS system. Spreading through the sequence of pseudo-noise (PN) to send the right message to data modulation to achieve. On the receiving end, the original pseudo-noise sequence and the received signal may be related Operational narrowband interference signal DS extended to the whole band, make tampering equivalent to a lesser extent than the flat spectrum of noise; Meanwhile, the DS signal disspreaded restore the original data.

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
