Achieving Full DoF in Heterogeneous Parallel Broadcast Channels with Outdated CSIT
Jinyuan Chen, Sheng Yang, Ayfer Ozgur +1
We consider communication over heterogeneous parallel channels, where a transmitter is connected to two users via two parallel channels: a MIMO broadcast channel (BC) and a noisele…
Feedback through Overhearing
Jinyuan Chen, Ayfer Ozgur, Suhas Diggavi
In this paper we examine the value of feedback that comes from overhearing, without dedicated feedback resources. We focus on a simple model for this purpose: a deterministic two-h…
Capacity Approximations for Gaussian Relay Networks
Ritesh Kolte, Ayfer Özgür, Abbas El Gamal
Consider a Gaussian relay network where a source node communicates to a destination node with the help of several layers of relays. Recent work has shown that compress-and-forward…
When are dynamic relaying strategies necessary in half-duplex wireless networks?
Ritesh Kolte, Ayfer Özgür, Suhas Diggavi
We study a simple question: when are dynamic relaying strategies essential in optimizing the diversity-multiplexing tradeoff (DMT) in half-duplex wireless relay networks? This is m…
Near Optimal Energy Control and Approximate Capacity of Energy Harvesting Communication
Yishun Dong, Farzan Farnia, Ayfer Özgür
We consider an energy-harvesting communication system where a transmitter powered by an exogenous energy arrival process and equipped with a finite battery of size commun…
Channel Diversity needed for Vector Space Interference Alignment
Cheuk Ting Li, Ayfer Özgür
We consider vector space interference alignment strategies over the -user interference channel and derive an upper bound on the achievable degrees of freedom as a function of th…
