Conversion Loss for the Quantizer of GPS Civil Receiver in Heavy Wideband Gaussian Noise Environments

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.
