Title
Feasibility of HPA Linearization System using Amplitude Reference Pilot Signal.
Abstract
Broadband wireless systems need to achieve high spectrum efficiency as well as high power efficiency of HPA (High Power Amplifier). When HPA is used with low output back-off (OBO), increased ACLP (Adjacent Channel Leakage Power) results in significant ACI (Adjacent Channel Interference) especially in TDD (Time Division Duplexing) wireless systems due to a near-far problem. In order to solve this ACLP problem of HPA at a mobile terminal, this paper proposes a novel HPA linearization system using amplitude reference pilot signal which is used to measure input-output characteristics of HPA of a mobile terminal at a base station. It describes design and performance of amplitude reference pilot signal and shows ACLP improvement to confirm the feasibility of the proposed HPA linearization system.
