  • Method for detecting received signal sequences
    Patent number: 5822375
    Abstract: This invention is a method for detecting received signal sequences of a communication system transmitting differentially encoded MPSK (Multiple Phase Shift Keying) signal sequences. This invention uses previously received signal samples and previously decided data phases to generate a phase reference for the current operation of detecting the received signal sample. The phase reference can be easily generated by a recursive form.
    Type: Grant

  • Method for detecting differently encoded signal sequences using a recursively computed reference signal
    Patent number: 5805642
    Abstract: This invention is a method for the detecting received signal sequences of a communication system transmitting a differentially encoded MPSK (Multiple Phase Shift Keying) or a differentially encoded 2MAPSK (2M-level Amplitude/Phase Shift Keying) signal sequence. The operation of detecting the currently received signal sample is based on a signal reference which is recursively generated by two or more previously generated signal references.
