Physical Layer (PHY)

This package provides a differentiable link-level simulator.

It seamlessly integrates multiple communication system elements, includingforward error correction (FEC),multiple input multiple output (MIMO) systems,orthogonal frequency division multiplexing (OFDM), and a rangeofwireless andopticalchannel models. It also supports simulation of some5G NR compliant features.

The best way to get started is by going through some of theTutorials.

Advanced users may want to consult theDeveloper Guidesfor a deeper understanding of the inner workings of Sionna PHY and to learn how toextended it with custom physical layer algorithms.
