详细介绍了微弱信号的检测方法 ,做信号检测的可以参考下其中的经典方法(Details of the weak signal detection methods, signal detection can be done under one of the classical method of reference)

Matlab开发的Smith原图演示软件(Smith chart demo developed by matlab)

◆输入数据： 由键盘输入待查文本文件名和待查单词。待查文件名为：input.txt。 ◆输出数据： 输出文件为output.txt，该文件第一行为该单词在文件中出现的次数。 从每二行开始是依先后次序输出的包含该单词的句子。 (◆ Input data: text file name to be examined by the keyboard input and searching words. Unknown origin file name: input.txt. ◆ Output data: output file output.txt, the first acts of the file of the word the number of occurrences in the document. From the beginning of every second line is output in the order in which the word sentences.)
