On the Error Exponents of ARQ Channels With Deadlines
Praveen Kumar Gopala, Young‐Han Nam, Hesham El Gamal · IEEE Transactions on Information Theory · 2007
In this correspondence, we consider communication over automatic repeat request (ARQ) memoryless channels with deadlines. In particular, an upper bound L is imposed on the maximum number of ARQ transmission rounds. In this setup, it is shown that incremental redundancy ARQ outperforms Forney's memoryless decoding in terms of the achievable error exponents.
