Popis: |
Simultaneous transmit and receive systems (STAR) are proposed to double the spectral efficiency and enhance spectrum utilization in the traditional microwave band. A major problem is high power self-interference (SI) due to the proximity of the transmit and receive antennas. In this paper, we propose to significantly improve system-level performance using a novel high isolation RF front-end based on collocated Tx/Rx antenna pair(s). Among our improvements, we propose a novel architecture for a STAR system incorporating four stages of self-interference cancellation across the propagation, analog, and digital domains. We aim to attain at least 120dB of total SI cancellation over a >100MHz bandwidth. |
