On the Effect of Interference on the Average Degrees of Freedom in MIMO Fading Ad-Hoc Networks
— We consider MIMO fading ad-hoc networks with Rayleigh co-channel interference (CCI) where, L transmitter/receiver pairs communicate independent information over the network, si...

Cooperative communications with relay-selection: when to cooperate and whom to cooperate with?
Abstract--In this paper, we propose a new cooperative communication protocol, which achieves higher bandwidth efficiency while guaranteeing the same diversity order as that of the ...

On the Feedback Capacity of Power Constrained Gaussian Noise Channels with Memory
—For a stationary additive Gaussian-noise channel with a rational noise power spectrum of a finite-order L, we derive two new results for the feedback capacity under an average ...
