Abstract :
In this paper, we propose a novel approach to cancel Self-interference (SI) signal in analog domain in Full-duplex (FD) communication system. This approach is based on self-mixing and called Self-Mixed Self-Interference Analog Cancellation (SM-SIAC) where three feedback loops are employed for auto-tuning. In condition that these loops converge, we analyze the cancellation performance.
