Extensions beyond discrete memoryless channels

Extend joint identification and sensing with noisy strictly causal feedback from state-dependent discrete memoryless channels to Gaussian channels, multiuser settings, and quantum communication systems.

Background

This work focuses on state-dependent discrete memoryless channels with noisy strictly causal feedback. Many practical and theoretical scenarios involve continuous alphabets (e.g., Gaussian channels), multiple terminals (multiuser networks), or non-classical channel models (quantum systems).

Extending the JIDAS framework to these settings would broaden applicability to 6G-relevant scenarios and could reveal fundamentally different identification–sensing tradeoffs and feedback roles.
