FSK-OOK-PSK-ASK

  • The Viterbi algorithm is the same as the binary case with one main difference: The survivor sequence

    The Viterbi algorithm is the same as the binary case with one main difference: The survivor sequences include the uncoded bits, which are decided at each trellis stage when selecting one of two parallel branches with the largest correlation metric. Presently, only 8-PSK modulation is considered. Extensions to higher-order modulations can be implemented following a similar procedure.

    This tutorial attempts to get you started developing with the Win32 API as quickly and clearly as possible. It is meant to be read as a whole, so please read it from beginning to end before asking questions... most of them will probably be answered. Each section builds on the sections before it. I have also added some solutions to common errors in Appendix A. If you ask me a question that is answered on this page, you will look very silly.
