Full Duplex Wireless Systems

Speaker: Dr. Vanneet Aggarwal

Host Faculty: Professor Elza Erkip

Abstract

Nodes in WiFi and cellular today cannot send and receive at the same time and frequency. This is mainly because of the self-interference from the transmitter to the receiver at the same node. Recent results have shown promising designs showing that self-interference can be cancelled for use in short-range communications achieving higher throughputs. I will describe the work done by researchers at AT&T Labs in collaboration with other universities to achieve two-way communication and achieving higher throughputs. We give novel Physical and MAC layer designs which demonstrate the feasibility in WiFi type domains. Further extensions to cellular infrastructure will also be discussed.
