Causal-CSIT Rate Adaptation for Block-Fading Channels
We propose a rate-adaptive error-correction coding framework for transmission over finite-length block-fading chan- nels, with causal channel state information at the transmitter. A dynamic programming optimization approach can be use to obtain the optimal rate adaptation strategy. A suboptimal rate adaptation strategy is developed for sequential random codes. Numerical results show that significant performance gains are achievable with the proposed adaptation scheme.
