Exploiting fading dynamics along with AMC for energy-efficient transmission over fading channels


The basic adaptive modulation and coding (AMC) in its lowest mode blindly transmits the frames without payload during outages, which wastes energy. In this letter, we propose to exploit fading dynamics (FD) along with AMC to achieve a higher energy efficiency. In the proposed FD-AMC approach, the frame transmission is suspended judiciously during the outages, thereby saving energy, particularly in harsh channel conditions. © 2011 IEEE.
