Distributed Universally Optimal Strategies for Interference Channels with Partial Message Passing
Vaneet Aggarwal, Salman Avestimehr, Ashutosh Sabharwal
In distributed wireless networks, nodes often do not know the topology (network size, connectivity and the channel gains) of the network. Thus, they have to compute their transmiss…
On Channel Output Feedback in Deterministic Interference Channels
Achaleshwar Sahai, Vaneet Aggarwal, Melda Yuksel +1
In this paper, we study the effect of channel output feedback on the sum capacity in a two-user symmetric deterministic interference channel. We find that having a single feedback…
Ergodic Layered Erasure One-Sided Interference Channels
Vaneet Aggarwal, Lalitha Sankar, A. Robert Calderbank +1
The sum capacity of a class of layered erasure one-sided interference channels is developed under the assumption of no channel state information at the transmitters. Outer bounds a…
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…
