Entropy and Channel Capacity under Optimum Power and Rate Adaptation over Generalized Fading Conditions

open access: yes, 2015
Accurate fading characterization and channel capacity determination are of paramount importance in both conventional and emerging communication systems. The present work addresses the nonlinearity of the propagation medium and its effects on the channel ...

Almost universal codes for fading wiretap channels

open access: yes, 2016
We consider a fading wiretap channel model where the transmitter has only statistical channel state information, and the legitimate receiver and eavesdropper have perfect channel state information.
