강한 광대역정규잡음 환경에서 GPS 상용 수신기 양자화기의 변환 손실 분석

Abstract

This paper has derived the conversion loss according to the synchronized condition between the transmitted and locally generated spreading signals for the civil global positioning system (GPS) receiver in the heavy wideband Gaussian noise environments. From this, the outputs of the 2-bit nonuniform quantizer, which has the minimum conversion loss, is set to and , while the quantization step size is approximated to the jamming-to-signal power ratio.
