RF Signal Capture Using MATLAB and SDR

The Pluto Radio, USRP® Embedded Series Radio and Xilinx® Zynq®-Based Radio support packages from Communications Toolbox™ can be used to capture RF signals off the air using Software Defined Radio (SDR) hardware. Using a simple-to-use MATLAB® interface, any signal can be captured either into the MATLAB workspace or directly to a file for post-capture processing in MATLAB and Simulink®. First, the capture function is used to record the FM Broadcast spectrum to a file which is later read back into a DSP System Toolbox™ spectrum analyzer that highlights peaks corresponding to local broadcast stations. Next, the capture function is used to receive an LTE frame from a local antenna to the MATLAB workspace. LTE Toolbox™ is then used to decode the known physical cell identifier to verify reception.
