AWGN Channel Capacity of Energy Harvesting Transmitters with a Finite Energy Buffer
Deekshith P K, Vinod Sharma, R Rajesh
We consider an AWGN channel with a transmitter powered by an energy harvesting source. The node is equipped with a finite energy buffer. Such a system can be modelled as a channel…

On Secrecy above Secrecy Capacity
R. Rajesh, Shahid M. Shah, Vinod Sharma
We consider secrecy obtained when one transmits on a Gaussian Wiretap channel above the secrecy capacity. Instead of equivocation, we consider probability of error as the criterion…
