Queuing Theoretic Models for Multicast and Coded-Caching in Downlink Wireless Systems
Mahadesh Panju, Ramkumar Raghu, Vinod Sharma +1
We consider a server connected to users over a shared finite capacity link. Each user is equipped with a cache. File requests at the users are generated as independent Poisson…
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…
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…
