Software-Defined Radio (SDR)

Design FPGA- and DSP-based software radios

Software-defined radio (SDR) enables the design of advanced communications systems that use OFDM, MIMO, and cognitive radio techniques. These SDR designs are often implemented using an FPGA, a DSP, or both.

MATLAB and Simulink provide an open, integrated SDR development environment for:

• Radio-in-the-loop design using USRP^® devices from Ettus Research LLC^™
• Physical (PHY) layer design
• Control plane design

For SDR designs, MATLAB and Simulink enable:

• Simulation acceleration with parallel computing and GPUs
• C and HDL code generation and cosimulation
• Processor-in-the-loop design verification
• FPGA-in-the-loop design verification
