A Comprehensive Self-interference Model for Single-antenna Full-duplex Communication Systems



  1. NSF CCF CIF CAREER Award 1453426

Problem Statement and Motivation 

  • Promoted by the popularity of small cell wireless systems, recent works have provided experimental evidence and methodologies for full-duplex communication.
  • We aim to create highly reliable full-duplex wireless networks.

Technical Approach

  • We improve full-duplex communication by reducing the self-interference.
  • We offer a comprehensive SI model for single-antenna full-duplex systems based on direct-conversion transceiver structure considering nonlinearities of all the transceiver radio frequency (RF) components, in-phase/quadrature (IQ) imbalances, phase noise effect, and receiver noise figure.
