Communications Toolbox™ provides algorithms and apps for the design, end-to-end simulation, analysis, and verification of communications systems. Toolbox algorithms including modulation, channel modeling, equalization, and filtering, enable you to compose and simulate a physical layer model of your standard-based or custom-designed wireless communications system.

The toolbox includes a Waveform Generator app that enables you to create, impair, visualize, and export modulated waveforms, and transmit them over the air. Furthermore, it offers visualization capabilities through constellation and eye diagrams, spectrum analyses, and time-domain plots. The toolbox includes RF impairments, such as memoryless amplifier nonlinearity and carrier offset and compensation algorithms, including carrier and symbol timing synchronizers. These algorithms enable you to realistically model link-level specifications and compensate for the effects of channel degradations.

Communications Toolbox enables AI-based wireless problem-solving. It supports spectrum monitoring, signal classification, and intelligent transceiver design with AI techniques using synthesized or captured over-the-air (OTA) data. You can perform OTA testing using SDRs to compensate for the effects of channel degradations and verify your designs.
