Multipathndirect-path signals distort the received signal and cause errors in code and phase measurements. Differential techniques do not eliminate multipath and thus multipath is an important error source in high precision applications. The physical surroundings around the receiver’s antenna dictate the mul填料 发表于 2025-3-26 17:40:43
Interferenceng. It offers a systematic treatment of natural, unintentional, and intentional interference, with emphasis on intentional jamming and spoofing. Theoretical performance bounds are developed for the simplest cases of narrowband and wideband interferences. The chapter finishes with a review of the sta
