Information Capacity of an Energy Harvesting Sensor Node
Rajesh Ramachandran, Vinod Sharma, Pramod Viswanath
Energy harvesting sensor nodes are gaining popularity due to their ability to improve the network life time and are becoming a preferred choice supporting 'green communication'. In…
Quasi-Orthogonal Space-Time-Frequency Trellis Codes for MIMO-OFDM Systems
J. Robinson Ebi Elias, R. Rajesh
The main objective of this project is to design the full-rate Space-Time-Frequency Trellis code (STFTC), which is based on Quasi-Orthogonal designs for Multiple-Input Multiple-Outp…
Capacity of Gaussian MAC Powered by Energy Harvesters without Storage Buffer
R Rajesh, Deekshith P K, Vinod Sharma
We consider a Gaussian multiple access channel (GMAC) where the users are sensor nodes powered by energy harvesters. The energy harvester has no buffer to store the harvested energ…
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…
