Inherent Self-Interference Cancellation (SIC)
Sponsors:
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 use the inherent secondary SI signal at the circulator, reflected by the antenna, to cancel the primary SI signal leaked from the Tx port to the Rx port.
