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:
(NXY×LX×LY)MOD(LX×LZ)=LX
wherein Nxy=integer number of LxLy 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.
