Abstract:
1. A receiver for acquiring composite pseudo-noise (PN) encoded signals, the receiver comprising: a receiver demodulator wherein the receiver demodulator is adapted to generate a normalized epoch autonomous phase (NEAP), wherein the NEAP comprises the form: wherein N xy =integer number of L x L y epochs of interests, and L (PN..*PN...) =epoch length of PN component codes; a first receiver clock generator; at least three first receiver pseudo-noise (PN) component code generators coupled to the first receiver clock generator; a receiver logic combiner coupled to the at least three first receiver PN component code generators, the receiver logic combiner adapted to generate a local epoch symmetrical composite PN code, wherein the local epoch symmetrical composite PN code comprises at least three PN component codes; wherein the at least three PN component codes are relatively prime.
