People pay more and more attention to the issue of GPS (global positioning system) anti-jamming nowadays, and the research on blind GPS anti-jamming receiver has more practical significance. Aiming at this, a technique of blind GPS anti-jamming receiver based on constant modulus (CM) array is analyzed in detail, in which the CM property of GPS signal is utilized, and the paper specially gives the...
The performance of various carrier recovery loop architectures (phase lock loop (PLL), Doppler-aided PLL, frequency lock loop (FLL), and Doppler-aided FLL) in tracking weak GPS signals are analyzed and experimentally validated. The effects of phase or frequency detector design, oscillator quality, coherent averaging time, and external Doppler aiding information on delaying loss of lock are quantified...
