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

Description: 分析了在超宽带通信系统中的扩频干扰，并用两种通用的调制技术实现了对提出的抗干扰方法的仿真-he ultra wideband (UWB) interference to direct
sequence spread spectrum (DSSS) receiver is analyzed. Two
popular UWB modulation schemes, the time hopping pulse
position modulation (TH-PPM) and time hopping pulse
amplitude modulation (TH-PAM), are considered. The pulse
repetition rate (T’RR) of UWB signal and the freqnency hand of
the DSSS play the primary roles in the BER performance of the
DSSS receiver in the presence of UWB interference. The UWB
signal parameters raising the interference to DSSS receiver are
discussed. The characteristics of an aggregation of multiple
UWB signals are somehow different from that of a single UWB
device, especially for the TB-PPM scheme, where discrete
spectral lines maybe exist in the band of DSSS receiver. The
system parameters of TH-PPM such as the modulaiion index
and maximum shift incurred hy the time hopping code
determine the amplitude of the discret
