Communications Systems

MATLAB® and Simulink® products provide a complete environment for design, simulation, and verification of wireless systems. You can:

  • Simulate wireless communication systems from antenna to bits.
  • Design smart RF systems.
  • Test wireless designs with SDR hardware and RF instruments.
  • Analyze, simulate, and test LTE/LTE-A standard-compliant systems.
  • Simulate defense and automotive radar systems.

Antenna-to-Bits Simulation

Model the physical layer of your wireless communications systems in MATLAB and Simulink before building them. Compose test benches that provide complete executable specifications of your designs, extending from information bits to signals radiating on antennas. Perform simulation to optimize parameters, examine what-if scenarios, and iterate quickly on designs. Test your designs and verify system-level performance using a suite of visualization and measurements tools, including configurable spectrum analyzers and scopes.

With Communications System Toolbox™ and related wireless design products, you can:

  • Analyze signals and make performance measurements such as EVM, ACLR, BLER.
  • Incorporate algorithms such as MIMO, OFDM, and beam-forming into your models.
  • Generate waveforms and create verification reference signals for downstream implementation.

Smart RF Design

Smart RF systems consist of digitally controlled, tunable RF front ends that can adapt to different operating conditions. With Simulink and SimRF™, you can model and simulate the RF transceiver together with baseband algorithms and analog/mixed-signal components. In addition, you can model them in a closed-loop configuration. This allows you to analyze complex algorithms and rapidly explore many different scenarios to the optimize system performance in the presence of RF impairments. You can:

  • Model smart RF architectures.
  • Develop calibration and control algorithms such as DPD or AGC to mitigate impairments and interferers.
  • Add measured RF component characteristics.
  • Use circuit envelope techniques to simulate RF transceivers an order of magnitude faster than circuit simulations.
