你是要去斯卡布罗集市吗？那里青菜3块一斤，牛肉20块一斤。

Before running the programs, make sure you have Communications Toolbox Support Package for Analog Devices ADALM-Pluto Radio ready. Connect ADALM-PLUTO to your computer, and run

sdrdev('Pluto');
configurePlutoRadio('AD9364')

in MATLAB for only once, which assures that your Pluto can handle FM frequency.

Rx.m works as a radio receiver. You can listen to all the commercial FM radio programs.

Tx.m builds your own broadcasting station by transmitting FM signals! The default content is Scarborough Fair.flac. You can enjoy the music via radio app in your smartphone! BE AWARE THAT broadcasting radio signals without permission can be illegal. DO NOT use an occupied frequency!

RT.m is a test of real-time duplexing. It requires accurate controls of hardware. Do not change the size of buffers. Otherwise the signals processed in Pluto may break off and be lost!

I understand that you may want a program to broadcast your real-time speech. I probably will not be available to develop such a program. You may first build a real-time recording program, and then FMmodulate every frame to broadcast them.
