Secrecy capacity of a class of orthogonal relay eavesdropper channels
Vaneet Aggarwal, Lalitha Sankar, A. Robert Calderbank +1
The secrecy capacity of relay channels with orthogonal components is studied in the presence of an additional passive eavesdropper node. The relay and destination receive signals f…
Two Models for Noisy Feedback in MIMO Channels
Vaneet Aggarwal, Gajanana Krishna, Srikrishna Bhashyam +1
Two distinct models of feedback, suited for FDD (Frequency Division Duplex) and TDD (Frequency Division Duplex) systems respectively, have been widely studied in the literature. In…
Diversity Order Gain with Noisy Feedback in Multiple Access Channels
Vaneet Aggarwal, Ashutosh Sabharwal
In this paper, we study the effect of feedback channel noise on the diversity-multiplexing tradeoff in multiuser MIMO systems using quantized feedback, where each user has m transm…
Distributed Joint Source-Channel Coding for arbitrary memoryless correlated sources and Source coding for Markov correlated sources using LDPC codes
Vaneet Aggarwal
In this paper, we give a distributed joint source channel coding scheme for arbitrary correlated sources for arbitrary point in the Slepian-Wolf rate region, and arbitrary link cap…
On Maximizing Coverage in Gaussian Relay Networks
Vaneet Aggarwal, Amir Bennatan, A. Robert Calderbank
Results for Gaussian relay channels typically focus on maximizing transmission rates for given locations of the source, relay and destination. We introduce an alternative perspecti…
