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: 小波变换的一级分解过程是，原始信号分别进行低通、高通滤波，再分别进行二元下抽样，就得到低频、高频（也称为平均、细节）两部分系数；而多级分解则是对上一级分解得到的低频系数再进行小波分解，是一个递归过程。-Wavelet decomposition level is, the original signal were low-pass, high pass filter, and then carried out under the binary sample, we obtained low-frequency, high-frequency (also known as the average, details) coefficient of two parts and multi-level decomposition it is the decomposition level to be low-frequency coefficients further wavelet decomposition is a recursive process.

Description: JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute.
Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets a systematic way of dealing with datasets having components of non-uniform length tools for fine-tuning figures using compact, straightforward statements and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.

Description: 这个是Delphi 2007下写的，需要Indy的ICMP控件 (Delphi2006应该也能编译，因为都带的是Indy10)
原理就是多线程Ping一个网关下的所有主机，然后导出ARP缓存。
因为Ping前会发出ARP请求获取每个IP的MAC地址，所以在Ping完后用 arp -a 取得本机ARP缓存。
最后就是读入arp -a 的返回，并存起来备查。-This is written under Delphi 2007 and need to Indy the ICMP control (Delphi2006 should be able to compile, because both bands are Indy10) principle is a multi-threaded gateway Ping all hosts, and then export the ARP cache. Ping will be issued because the previous ARP request to obtain the MAC address for each IP, so after Ping using arp-a to obtain the local ARP cache. Finally is read into the arp-a return, both up for future reference.

Description: National Instruments LabView software has a native file format called LabView Measurement File (LVM, extension .lvm). This m-file, lvm_import.m, reads LVM files and imports the data into the MATLAB workspace.
LVM is an ascii text file format, and the data can be imported into MATLAB using the built-in import.m function. However, import.m has some limitations: it cannot handle multi-part LVM files, and it does not return the contents of the file and section headers. lvm_import.m handles all types of LVM files, and returns specific information such as date, time, data column names, etc. -National Instruments LabView software has a native file format called LabView Measurement File (LVM, extension.

Description: M序列信号算法仿真在系统辨识中有着很大的应用前景。多谐差相方法辨识精度很高有着很苛刻的要求，要求已知辨识参数个数已知并且需要整周截断。而M序列信号的测试方法没有这个方面的要求。其辨识未知模型时，可以用最小二乘算法观察辨识系统的精度来确定模型的阶次。本算法里面不但给出了用于M序列生成的本原多项式计算方法，同时编写了M序列信号的生成算法，并编写了相关辨识方法的算法。-M sequence signal simulation algorithm for identification in the system have great application prospects. Identification of multi-harmonic differential phase method with high precision has very stringent requirements, demand parameters are known to identify the number of known and need to cut off the whole week. The M sequence signal testing methods do not have this requirements. Its identification unknown model, you can observe the identification system using least-squares algorithm to determine the accuracy of the model order times. This algorithm is used which not only gives the M sequence generated by primitive polynomial method of calculation as well as prepare the M sequence signal generation algorithm, and the preparation of the relevant identification method algorithms.
