Abstract:
1. A multipath discriminator module for a communications and/or navigation system that implements spread spectrum modulation, wherein the module has an input suitable for receiving navigation signals, a sampler for supplying sampled signals at a frequency twice the apparent frequency (fc) of a code of said navigation signals, and a submodule for calculating an error signal (e k ) from said sampled signals (r k+1/2 ), and a locally generated spreading code (C |K|L ) wherein: “K “h “Z “ “β” designating the attenuation factor of the SRC signal “Sβ” is an offset “Tc” designating a duration of one bit of a pseudo-noise sequence “t1” is a first sampling instant and “t2” is a second sampling instant.
