초록

본 논문에서는 새로운 해석을 통해서 RFIC에서 사용하는 범용 I/Q 부정합 보상기를 사용하여 다중 접합 기반 수신기에서 I 채널과 Q 채널 정보 신호를 생성할 수 있음을 증명한다. 이 증명으로 다중 접합 기반 수신기를 기존의 RFIC 기반 시스템에 추가적인 디지털 신호 처리 기능 없이 집적할 수 있다. 이 논문에서는 다중 접합기의 I/Q 재생성 파라미터의 정확도와 I/Q 부정합 사이의 관계를 분석하고, 추정 결과와 모의 실험 결과가 거의 일치함을 보인다.

This paper proves that multi-port junction-based direct receivers (MPDRs) can regenerate I- and Q-channel signals accurately by using conventional I/Q mismatch compensation. This proof enables MPDRs to be integrated into existing RFIC based systems without additional digital signal processing. This paper analyzes the relationship between accuracy of I/Q regeneration parameters and degree of I/Q mismatch, and shows that the estimation results and the simulation results are almost the same.
