Four-Tap RF Canceller Evaluation for Indoor In-Band Full-Duplex Wireless Operation

Abstract

Analog self-interference mitigation techniques are currently being investigated in a variety of operational settings for In-Band Full-Duplex (IBFD) systems. The significant multipath effects of realistic environments, such as inside buildings, can severely limit performance. The influence of different transceiver parameters on the effectiveness of a four-tap RF canceller, built using a tapped delay line architecture, was characterized with a set of indoor measurements. The prototype canceller showed up to 30 dB of cancellation over bandwidths ranging from 10 to 120 MHz centered at 2.45GHz, and produced a combined analog system isolation greater than 85 dB.
