This folder has some scritps that you may find usefull. All of it comes from questions that I ve received in my email. If you have a new request/question, feel free to send it to marceloperlin@gmail.com. But please, don t ask me to do your homework. Passing_your_param0 This folder contains instructions (and m files) for passing you own initial parameters to the fitting function. I also included a simple simulation script that will create random initial coefficients (under the proper bounds) and fit the model to the data.

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

CodezBank is just a small application that stores source code snippets organized in a hierarhichal maner with basic search ability. You just copy and paste the code snippet into or from this application via clipboard. If you have a bag of coding tricks then you want to keep them in this app.

As mentioned, most computers include a serial port. The only hardware setup required is connecting the serial cable to the serial port on the PC and the serial port on the instrument. The serial instrument may include some hardware drivers or software utilities for communication, and should include documentation on the baud rate, packet size, stop bits, and parity bits that the instrument will use. Additionally, check the National Instruments Instrument Driver Network to see if LabVIEW drivers already exist for yout instrument, as

// This Communications Component is implemented using separate Read and Write // threads. Messages from the threads are posted to the Comm control which is // an invisible window. To handle data from the comm port, simply // attach a handler to OnReceiveData . There is no need to free the memory // buffer passed to this handler. If TAPI is used to open the comm port, some // changes to this component are needed ( StartComm currently opens the comm // port). The OnRequestHangup event is included to assist this. // // David Wann // Stamina Software // 28/02/96 // davidwann@hunterlink.net.au

词法分析是编制一个读单词的过程，从输入的源程序中，识别出各个具有独立意义的单词，即基本保留字、标识符、常数、运算符、分隔符五大类。并依次输出各个单词的内部编码及单词符号自身值。程序语言的单词符号一般分为五种：关键字（保留字/基本字）if、while、begin…；标识符：常量名、变量名…；常数：34、56.78、true、‘a’、…；运算符：+、-、*、/、〈、and、or、….、；界限符：， ； （ ） { } /*…。

基于UDP实现E-Mail传输 工作过程描述： 客户端描述： 1． Client（以下简称C端）端将邮件以规定的大小封装为符合要求的UDP包。 2． 将封装好的UDP包发出，并等待Server(以下简称S端)端收到相应的UDP包后返回的回应Acknowledge(以下简称为ACK)。若收到的为Positive ACK,则继续发包；若收到的为Negtive ACK,则将应发的包重发。 3． 直到C端将所有要发的包都发完，并都已经收到S端的回应，最后发一个End包，直接关闭此进程。 服务器端描述： 1． S端启动服务进程，并监听相应端口。 2． 若收到C端发出的有关请求，按如下情况给出相应的反映： a． 将收到的包进行检测，若收到的包有错则抛弃（discard），并发给C端一个negtive ACK。 b． 将收到的包进行检测，若收到的包正常，则将此包进行解包，将内容输出至一临时文件；并发给C端一个positive ACK。 3．依次收到来自C断的包，直到收到end为止，并关闭此进程，转回监听状态。
