Abstract
A method is disclosed for tracking the phase of a received phase-modulated carrier carrying a sequence of symbols represented by phase jumps in a low signal-to-noise ratio environment. An input sequence of symbols stored in a delay line. The phase of a current symbol in a phase locked loop, and the phase error detected in the phase locked loop is updated to take into account phase error estimates of future symbols.
