An Interference Aware RF Receiver Front-End Design for WiMAX Application

Abstract

In this paper, an interference aware scheme (IAS) is proposed with RF receiver front-end design for WiMAX application. Adjacent channel interference and non-adjacent channel interference can be sensed via the proposed scheme for the adjustment of RF front-end linearity performance which corresponds to system interference tolerance and hence avoids unnecessary power consumption. A CMOS implementation for the RF receiver front-end with IAS has been designed to demonstrate the feasibility.
