A Layered Lattice Coding Scheme for a Class of Three User Gaussian Interference Channels
Sriram Sridharan, Amin Jafarian, Sriram Vishwanath +2
The paper studies a class of three user Gaussian interference channels. A new layered lattice coding scheme is introduced as a transmission strategy. The use of lattice codes allow…
Capacity of Symmetric K-User Gaussian Very Strong Interference Channels
Sriram Sridharan, Amin Jafarian, Sriram Vishwanath +1
This paper studies a symmetric K user Gaussian interference channel with K transmitters and K receivers. A "very strong" interference regime is derived for this channel setup. A "v…
Communication Through Jamming over a Slotted ALOHA Channel
Sandeep Bhadra, Shreeshankar Bodas, Sanjay Shakkottai +1
This work derives bounds on the jamming capacity of a slotted ALOHA system. A system with n legitimate users, each with a Bernoulli arrival process is considered. Packets are tempo…
Adaptive Sum Power Iterative Waterfilling for MIMO Cognitive Radio Channels
Rajiv Soundararajan, Sriram Vishwanath
In this paper, the sum capacity of the Gaussian Multiple Input Multiple Output (MIMO) Cognitive Radio Channel (MCC) is expressed as a convex problem with finite number of linear co…
Relay Subset Selection in Wireless Networks Using Partial Decode-and-Forward Transmission
Caleb K. Lo, Sriram Vishwanath, Robert W. Heath
This paper considers the problem of selecting a subset of nodes in a two-hop wireless network to act as relays in aiding the communication between the source-destination pair. Opti…
Scheduling and Pre-Conditioning in Multi-User MIMO TDD Systems
Jubin Jose, Alexei Ashikhmin, Phil Whiting +1
The downlink transmission in multi-user multiple-input multiple-output (MIMO) systems has been extensively studied from both communication-theoretic and information-theoretic persp…
