SDR_FM_Radio\n\n[![npm](https://img.shields.io/npm/l/express.svg)](https://github.com/MeowLucian/SDR_FM_Radio/blob/master/LICENSE)\n\nUsing Software Designed Radio to transmit \u0026 receive FM signal.\n\nTransmitter and Receiver hardware : Zedboard (Xilinx Zynq®-7000) + AD9361 (Analog Device-FMCOMMS3)\n\n![Hardware](https://raw.githubusercontent.com/MeowLucian/SDR_FM_Radio/master/Image/Hardware.jpg)\n\n# Software needed :\n\n* Matlab R2017b\n* support package for Xilinx Zynq-Based Radio (R2017b version)\n\nBefore 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.\n\n# Simulink Diagram :\n\nOpen `FM_radio_TX.slx` Simulink model.\n\nDouble click `From Multimedia File` block and edit the path to import the example music files.\n\nRun `FM_radio_TX.slx` to transmit FM signal.\n\n![GUI_TX_Simulink_Block_Diagram.png](https://raw.githubusercontent.com/MeowLucian/SDR_FM_Radio/master/Image/GUI_TX_Simulink_Block_Diagram.png)\n\n# GUI :\n\n## Transmitter (Zedboard + AD9361)\n\n* Center Frequency Setting\n\nDefault : 100 MHz\n\n\u003cimg src=\"https://raw.githubusercontent.com/MeowLucian/SDR_FM_Radio/master/Image/GUI_TX_Simulink_Center_Frequency_Change.png\" width=\"500\"\u003e\n\nNotice : antenna length must be `light speed / Center Frequency / 2` = `3*10^8 / 100*10^6 / 2` = `1.5 meters`\n\n(Half wave length) for better transmitting in this example\n\n* Music Time Scope\n\n\u003cimg

music.\n\n* Change the carrier frequency.\n\n* Import your own music (Notice : audio sample rate must be 48000 Hz in this example)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FMeowLucian%2FSDR_FM_Radio","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FMeowLucian%2FSDR_FM_Radio","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FMeowLucian%2FSDR_FM_Radio/lists"}
