Software-Defined Radio (SDR) Build software-defined radios (SDRs) with MATLAB What is an SDR? A software-defined radio (SDR) is a wireless communication system whose functionality can be configured using software or programmable hardware. Traditional radio transmitters and receivers can usually send and receive a single type of signal. Software-defined radios are more versatile. Using different software configurations, SDR hardware can communicate at different frequencies using multiple wireless standards such as Bluetooth, FM radio, Wi-Fi, GPS, and LTE technology.

A software-defined radio has a significant portion of the system defined in software. This has several advantages: ease of development, flexibility in reconfiguration, and cost effectiveness. SDRs typically consist of

Development Workflow An optimal workflow for developing SDRs involves designing and verifying the system in a single development environment. SDR hardware can be incorporated into your design in two ways: 1. Input and Output (I/O) – Connect and configure your SDR hardware to send and receive live radio signals using the transmitter and receiver terminals of the radio. Process these signals on the host, for rapid prototyping of the transmitter and receiver algorithms. 2. Target – Deploy the code onto the FPGA or SDR hardware platform. You can either program the FPGA with the precompiled bitstream file or generate HDL code from your design, compile the code, and program the FPGA. For more information, see Communications System Toolbox™ (with hardware support packages that connect wireless communication algorithms with supported SDR platforms) and HDL Coder™ (which generates HDL code for FPGAs), both for use with MATLAB® and Simulink®.
