BER Analysis of a Quadrature Receiver with an Autocalibration Function
자동보정 기능을 가진 Quadrature 수신기의 BER 해석
Abstract
In this paper the BER consideration of a quadrature receiver that has an autocalibration method is considered. The analysis is based on the derivation of the statistical characteristics of the imbalances in gain and phase between in-phase and quadrature components that may cause severe performance degradation of the receiver. The density. mean and variance functions of the estimates of gain and phase imbalances are discussed. Then it is shown that the estimates are asymptotically minimum variance unbiased with respect to the integration time in sampling. A brief consideration on the BER calculation follows.
