Design and simulate the physical layer of communications systems
Communications System Toolbox™ provides algorithms and apps for the analysis, design, end-to-end simulation, and verification of communications systems in MATLAB® and Simulink®. Toolbox algorithms, including channel coding, modulation, MIMO, and OFDM, enable you to compose a physical layer model of your system. You can simulate your models to measure performance.
The system toolbox provides constellation and eye diagrams, bit-error-rate, and other analysis tools and scopes for validating your designs. These tools enable you to analyze signals, visualize channel characteristics, and obtain performance metrics such as error vector magnitude (EVM). Channel and RF impairment models and compensation algorithms, including carrier and symbol timing synchronizers, enable you to realistically model your link-level specifications and compensate for the effects of channel degradation.
Using Communications System Toolbox hardware support packages, you can connect your transmitter and receiver models to radio devices and verify your designs with over-the-air testing. The system toolbox supports fixed-point arithmetic and C or HDL code generation.
Algorithms are available as MATLAB functions, System objects™, and Simulink blocks.

Using Communications System Toolbox hardware support packages, you can connect your transmitter and receiver models to external radio devices. This feature enables you to replace the simulated channels and impairments in your end-to-end model with live radio signals and then validate your design with over-the-air testing and software-defined radio (SDR) experiments.You can perform radio-in-the-loop simulations by a) generating custom waveforms in your baseband transmitter models, b) transmitting your waveform using SDR devices or instruments, c) capturing received samples with SDR devices or instruments, and d) processing received samples inside your baseband receiver models.
Radio-in-the-loop simulations: Hardware/instrument connectivity and Communications System Toolbox hardware support packages. You can generate baseband waveforms, transmit and receive live radio signals to and from RF instruments and supported SDR devices, and validate your communications system design with over-the-air testing.
Techniques such as MATLAB to C code generation, parallel processing, and GPU-optimized algorithms enable you to significantly speed up simulations of your communications models. The combined effect of using these acceleration methods may speed up a typical simulation by an order of magnitude, and also reduce the time needed to run a simulation overnight to just a few hours.
