Consistency in the face of change: an adaptive approach to physical layer cooperation
Ayan Sengupta, Yahya H. Ezzeldin, Siddhartha Brahma +2
Most existing works on physical-layer (PHY) cooperation (beyond routing) focus on how to best use a given, static relay network--while wireless networks are anything but static. In…
Network Simplification in Half-Duplex: Building on Submodularity
Martina Cardone, Yahya H. Ezzeldin, Christina Fragouli +1
This paper explores the {\it network simplification} problem in the context of Gaussian Half-Duplex (HD) diamond networks. Specifically, given an -relay diamond network, this pr…
Wireless Network Simplification : Beyond Diamond Networks
Yahya H. Ezzeldin, Ayan Sengupta, Christina Fragouli
We consider an arbitrary layered Gaussian relay network with layers of relays each, from which we select subnetworks with relays per layer. We prove that: (i) For arbit…
A Note on Antenna Selection in Gaussian MIMO Channels: Capacity Guarantees and Bounds
Yahya H. Ezzeldin, Ayan Sengupta, Christina Fragouli
We consider the problem of selecting antennas from a Gaussian MIMO channel with antennas, where and . We prove the fo…
