- Abstract
In processing global navigation satellite system(GNSS) signal, the signal-to-noise ratio(SNR) is weakened because of the quantization error of analog-to-digital converter(ADC). A theoretical calculation model of SNR is deduced after beamforming processing, and the influence of ADC quantization bits on the performance of anti-jamming GNSS receiver with antenna array is analyzed. When the number of antenna array is 7 and the ADC quantization bits are equal to 10, the analysis results of theoretical model and data simulation show that the maximum anti-jamming capacity is about 85 dB. By determining the relationship between the ADC quantization bits and the anti-jamming capacity of anti-jamming GNSS receiver, this conclusion provides a theoretical basis for ADC selection and design of anti-jamming GNSS receiver in engineering application.
