Using Software Designed Radio to transmit & receive FM signal.

Transmitter and Receiver hardware : Zedboard (Xilinx Zynq®-7000) + AD9361 (Analog Device-FMCOMMS3)

![Hardware](https://raw.githubusercontent.com/MeowLucian/SDR_FM_Radio/master/Image/Hardware.jpg)

# Software needed :

* Matlab R2017b

* support package for Xilinx Zynq-Based Radio (R2017b version)

Before executing this code, please follow this [tutorial](https://www.mathworks.com/help/supportpkg/xilinxzynqbasedradio/ug/install-support-package-for-xilinx-zynq-based-radio.html) to install support package for Xilinx Zynq-Based Radio in Matlab.

# Simulink Diagram :

Open `FM_radio_TX.slx` Simulink model.

Double click `From Multimedia File` block and edit the path to import the example music files.

Run `FM_radio_TX.slx` to transmit FM signal.

# GUI :

## Transmitter (Zedboard + AD9361)

* Center Frequency Setting

Default : 100 MHz



Notice : antenna length must be `light speed / Center Frequency / 2` = `3*10^8 / 100*10^6 / 2` = `1.5 meters`

(Half wave length) for better transmitting in this example

* Music Time Scope



* FM TX Signal Spectrum



## Receiver (Zedboard + AD9361)

Run `FM_radio_RX.m` to receive FM signal.



## Receiver (Mobile Phone)

Run FM app in your mobile phone

# Things to try yourself :

* Turn the switch to change the music.

* Change the carrier frequency.

* Import your own music (Notice : audio sample rate must be 48000 Hz in this example)
