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 ${\pm}1$ and ${\pm}2$, while the quantization step size is approximated to the jamming-to-signal power ratio.

본 논문에서는 강한 광대역정규잡음 환경에서 송신한 확산신호와 수신기에서 발생한 확산신호의 동기에 따른 2비트 비균등 양자화기의 변환손실을 (conversion loss) 분석하고, 이를 통해 변환손실이 최소인 2비트 비균등 양자화기의 출력은 ${\pm}1$, ${\pm}2$이고, 양자화 간격은 재밍 대 신호 전력비로 근사화할 수 있음을 보인다.
