ACPR Analysis of Millimeterwave OFDM System with Power Amplifier's Phase Distortion

전력증폭기 위상왜곡에 의한 밀리미터파 OFDM 시스템의 ACPR 해석

Abstract

Millimeterwave OFDM wireless LAN system has been modeled for ACPR analysis. With simple AM-to-PM modeling for power amplifier and system simulation technique, power amplifier ACPR is simulated for OFDM modulation, Also, amplifier back-off value satisfying the required ACPR and the ACPR degradation have been predicted with the measured and modeled AM-tn-PM distortion.

본 논문은 밀리미터파 OFDM 무선 랜 시스템의 ACPR(Adjacent Channel Power Ratio)영향을 모델링을 통하여 분석하였다. 전력 증폭기, 시스템 시뮬레이션기술을 분석하기 위하여 AM-to-PM 모델링을 사용하였다. 전력 증폭기 ACPR은 OFDM 변조(modulation)를 이용하여 시뮬레이션하였다. 증폭기의 back-off 값은 요구되는 ACPR을 만족시키며, ACPR감소치는 모델링한 AM-to-PM의 왜곡과 측정한 AM-to-PM의 왜곡을 이용하여 예측이 가능하였다.
