Autocorrelation sidelobe considerations in the characterization of multipath errors

The effects of autocorrelation sidelobes on multipath errors in pseudorandom noise (PRN) ranging systems are investigated. It is shown that both medium-delay (i.e., on the order of 1 PRN chip) as well as long-delay multipath errors are affected. Results are applied to the case of the Global Position...

Description
Summary:	The effects of autocorrelation sidelobes on multipath errors in pseudorandom noise (PRN) ranging systems are investigated. It is shown that both medium-delay (i.e., on the order of 1 PRN chip) as well as long-delay multipath errors are affected. Results are applied to the case of the Global Positioning System (GPS).
