What problem does it solve?

Simulating nonlinear, multi-carrier RF behavior end-to-end in MATLAB can be slow and error-prone when you try to assemble and manage Simulink models manually.

Core Features & Use Cases

• High-accuracy time-domain RF simulation: Runs an RF signal chain using the rfsystem System Object backed by RF Blockset, while keeping the workflow in MATLAB.
• Circuit-envelope vs. idealized baseband modes: Use CircuitEnvelope for highest accuracy (nonlinear compression, intermodulation, mismatch, multi-carrier) or IdealizedBaseband for faster simulations with stricter element support.
• Streaming and multi-port support: Stream frame-based input vectors through the System Object, model MISO receivers and SIMO transmitters, and handle zero-IF I/Q splitting.

Quick Start

Build an rfbudget for your RF chain, create an rfsystem from that budget, stream input frames into it with rfs(in), then release and close the auto-generated Simulink model with close_system(rfs, 0).
