1. A forward error correction system for a wireless receiver, comprising:

  • a symbol detector that correlates each received digital group of a packet with a selected symbol family and that provides a set of possible symbols and corresponding correlation factors for each digital group;

    a symbol selector, coupled to the symbol detector, that selects a plurality of possible symbols that have higher correlation factors for each digital group;

    CRC logic, coupled to the symbol selector, that calculates a plurality of possible CRC values for the packet using combinations of the plurality of possible symbols; and

    output logic, coupled to the CRC logic, that evaluates the plurality of possible CRC values to determine whether there is a correct symbol combination for the packet.
