Abstract

In this letter, IQ mismatch of a CA-supporting terminal for LTE-A is analyzed and each of the analog blocks is modeled mathematically. Based on the model, a new digital calibration algorithm is proposed and verified using simulation results.

본 논문에서는 LTE-A용 Carrier Aggregation 지원 단말의 IQ 불일치 (IQ Mismatch)를 분석하고 아날로그 블록 각각에 대해 IQ 불일치 모델을 수학적으로 유도한다. 그리고 이에 근거하여 디지털 보정 알고리즘을 제안하고 모의 실험을 통해 수신 성능을 평가한다.
