Choose a channel chain

Channel transformations are part of an editable generation configuration. Start from a retained template; do not copy legacy Hydra config-group commands or invent transformation registry names from older design notes.

rfgen init narrowband-baseline ./my-config
cd ./my-config
rfgen validate --config-dir .

The template’s channel.chain is the supported shape. Each entry contains a numeric transformation identifier and its params mapping. Change the YAML, validate it, then write to a new output path:

rfgen generate --config-dir . --output ./trial-output
rfgen inspect ./trial-output

Use Channels to understand the TX, propagation, RX-capture, and RX-hardware order. Use the Channel API for concrete transformation contracts. Sionna and site-specific ray-tracing examples in research material are not a supported copy-and-run CLI recipe.
