ABSTRACT:
A digital method and a digital processor for determining the in-phase and quadrature-phase components of a phase error of a detected signal. An incoming carrier signal is sampled directly, then combined with estimated phase data (derived in the computer) in the digital processor to derive in-phase and quadrature-phase components of phase error that are provided to the computer for derivation of a subsequent estimate of carrier phase data.
