Two channel Support for ADALM-PLUTO™

Description

This repo provides the necessary files to enable dual-channel operation of the ADALM-PLUTO™ radio in MATLAB® and Simulink®. It includes an example demonstrating frequency and phase synchronization between the two channels.

Requirements

• MATLAB
• Communications Toolbox™
• Communications Toolbox Support Package for ADALM-PLUTO Radio
• Rev C or Rev D ADALM-PLUTO
• A 1-2 power splitter

Contents

• RadioConfigurationManager.m
• ReceiveTwoChannelPhaseSynchronizedData.mlx
• configureTwoChannelPlutoRadio.m
• rx.p
• tx.p
• Security.md
• license.txt

Install Instructions

• Install Communications Toolbox Support Package for ADALM-PLUTO Radio
• Run below command in Matlab command window.

  spkgroot = matlabshared.supportpkg.getSupportPackageRoot();
  

• Dowload RadioConfigurationManager.m file and place in spkgroot/toolbox/shared/sdr/sdrplug/plutoradio_hspdef/plutoradio_hspdef/+plutoradio/+internal
• Download configureTwoChannelPlutoRadio.m and ReceiveTwoChannelPhaseSynchronizedData.mlx files and place in spkgroot/toolbox/shared/sdr/sdrplug/plutoradio_hspdef/plutoradio_hspdef
• Download tx.p and rx.p files and place in spkgroot/toolbox/shared/sdr/sdrplug/sdrplugins/plutoradio/+comm/+plutoradio

Agenda

• Connect the ADALM-PLUTO Radio: Attach the radio to your host computer and run the Hardware Setup App from the Communications Toolbox Support Package for ADALM-PLUTO Radio.
• Configure the Radio: Execute the configureTwoChannelPlutoRadio.m script to enable two-channel functionality on your ADALM-PLUTO.
• SMA Connections: Add SMA connectors to Tx2 and Rx2. Follow this page for connections
• Antenna Connection: Use a power splitter to connect the Tx1 antenna port of the radio to both the Rx1 and Rx2 ports.
• Run the Example: Execute the ReceiveTwoChannelPhaseSynchronizedData.mlx example to observe the dual channel operation.

Results

• Frequency Spectrum: The frequency spectrum of the data received from both channels will overlap, with peaks aligning at the same frequency.
• Phase Synchronization: The phase offset between channels will remain constant until the radio is released.
