ABSTRACT:
A method and apparatus for demodulating and decoding an MSK signal utilizing synchronous accumulation and simultaneous synchronization of reference carrier and MSK data clocks enables a GPS correlator channel in a multi-channel GPS receiver to be used for processing MSK signals. The PRN code epochs are synchronized with the MSK data clocks and the process of de-spreading with a PRN code is disabled in order to obtain coherent MSK demodulation without corrupting the MSK signal with a PRN code within the channel.
