Title :
Multipath and interference in spread-spectrum tracking systems
Author_Institution :
Delft Univ. of Technol., Netherlands
Abstract :
Multipath tracking errors are analyzed for both coherent and noncoherent delay lock loops with arbitrary early-late spacings, thereby extending the work presented to ION GPS-91, Albuquerque, NM, USA (Sept. 1991: Proceedings p.915-24). The ratios of fading bandwidth, loop bandwidth and data rate are crucial. Maximum absolute multipath pseudorange errors are proportional to early-late spacing, but aggravated by spread-spectrum signal filtering
