Deterministic Identification Codes for Fading Channels: Achieving Reliable Communication in Challenging Environments

The authors investigate deterministic identification (DI) codes for Gaussian AWGN, slow fading, and fast fading channels, proving new lower and upper bounds on the capacity of these channels. They show that DI codes can achieve significantly different capacity scaling compared to traditional Shannon message transmission, making them well-suited for event-triggered communication in next-generation wireless networks.
