A new technique is presented that can perfectly &&rat& two cochannel FM signals in a noiseless environment. The method involves the analytic solution of the phases to within one of two possibilities, and a two-state trellis algorithm to trace the correct sequence of phase solutions. This method represents an improvement over other cochanne! interference separatio2 methods (e.g., joint Viterbi and cross-coupled phase-locked loop) which can never perfectly separate the signals.
