免费软件作者还收费了真是的， OFDM传输的原理已经有很多资料介绍了，这里就不介绍了发送端：上面的流图将一个文本文件，打上TAG，再加上CRC32校验，构造成数据包，经过OFDM调制发射出去这里使用了plutosdr

研究了好一段时间的gnuradio，终于弄了一个大的项目出来，用两个AD936X结构的SDR实现了视频实时传输，话不多说，直接上效果：两个plutosdr架构的SDR，两台电脑，一个发射一个接收，发射端电脑读取

买高配的那个还可以的，mini版本的也行吧，mini版本比起plutosdr优势是接口是usb3.0的。plutosdr虽然便宜但是软件环境有些恶心，我对接gnuradio没成功过。
