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 Platform: |
