Adaptive Transmission of Variable-Rate Data over a Fading Channel for Energy-Efficiency
Adaptive Transmission Variable-Rate Data Fading Channel Energy-Efficiency
2015/8/17
Adapting to a time-varying channel to maximize the average information rate for a given power constraint is a well-understood problem. Important studies (e.g., [I], [Z], [3]) have developed optimal ra...
