SR-ARQ for MIMO OFDM Systems with Channel State Information Only at the Receiver
— In this paper, we compare two selective-repeat automatic-repeat-request (SR-ARQ) protocols for spatial multiplexing multiple-input multiple-output (MIMO) orthogonal frequency-d...

Adaptive Coding and Modulation for Hybrid ARQ Systems over Partially Observable Nakagami-m Fading Channels
— We study coding and modulation rate adaptation problem for HARQ systems with partially observable state from cross-layer viewpoint. The rate of convolutionally coded MQAM is ad...

Power-Efficient Resource Allocation for Time-Division Multiple Access Over Fading Channels
We investigate resource allocation policies for time-division multiple access (TDMA) over fading channels in the power-limited regime. For frequency-flat block-fading channels and ...
