ReflectFX — Full-Duplex Wireless Networks
Sponsors:
Problem Statement and Motivation
- Communication is asymmetrical and is becoming more so over time.
- Promoted by the popularity of small cell wireless systems, recent works have provided experimental evidence and methodologies for full-duplex communication.
- Backscatter modulation (BM) is based on the reflection of electromagnetic waves. BM takes advantage of the presence of reflection coefficient variations at the interface between the transmit antenna and the receiver input load. By varying the load, the reflection coefficient changes.
- We aim to create highly reliable full-duplex wireless networks by means of reflected power.
Technical Approach
- We develop a new framework for Backscatter-Modulation (BM) in fullduplex communication that efficiently captures the two-way flow of data over the same carrier at the same time.
- We establish theoretical foundations for full-duplex BM wireless networks by deriving exact and alternative capacity characterizations to serve as guideline in the transceiver design.
