QPSK
提出了一个采用(2,1,7)卷积码+QPSK的中频调制解调方案,并在Xilinx公司的100万
门FPGA芯片上实现了该系统。该系统在信噪比SNR为6dB左右时可实现速率超过1Mbit/s、误码率
小于10-5的数据传输。
(Proposed a use of (2,1,7) convolutional code+ QPSK modulation and demodulation of the IF program, and in Xilinx' s FPGA chip one million on implementation of the system. The system SNR to 6dB signal to noise ratio at about the rate may achieve more than 1Mbit/s, less than 10-5 bit error rate of data transmission.)

internet_down_load
分析一个文件夹及其子文件夹下所有的html文档,并查找文档中加载的png图片文件,通过urlwrite函数下载并保存png类型的图片文件到硬盘上。
此matlab代码用到了网络连接,下载,并且通过多线程技术,增加了下载的速度。
可以通过这个方法,下载网页中的内容,可以说想怎么下,就怎么下。(Analysis all the files of type html in a folder, find the documents that load png image file.Then download and save the png file to harddisk through urlwrite function .)
