EMMA-CSI-v1¶

v1 · proposed-contract

Task. E-CH-CSI (bridge) - see Tasks. What you predict. the CSI (channel state information) matrix. Target domain. COMMS - a bridge to the CSI camp.

Input¶

Raw complex multi-antenna I/Q (in-phase and quadrature), shape (num_rx, 2, N) float32, with per-scene metadata. 32- or 64-element massive MIMO (multiple-input multiple-output) array.

Labels¶

Channel matrix.

Splits¶

train and dev are public and regenerable; holdout is private and scored by prediction submission. Sample count to be pinned at v1.

Get it¶

emma download --dataset EMMA-CSI-v1 --split dev --out ./scenes

Metric¶

NMSE (normalized mean squared error, in dB). See Metrics.

What this tests¶

The channel matrix is a derived view computed from rfgen’s channel realization; the raw multi-antenna I/Q is the canonical record. This is a bridge task for CSI-native models.

How it is made¶

Generated by rfgen. The exact configuration (commit, emitters, channel, label extraction, seeds) is in the developer recipe.
