1. A method for error recovery in a wireless network after a collision between a transmission and some narrowband interference, wherein the transmission is decoded using a sequential decoder, the method comprising:

  • receiving the transmission;

    decoding the transmission;

    detecting the narrowband interference in the transmission;

    reconfiguring a digital signal processor to take into account the narrowband interference;

    backtracking over previously decoded portions of the transmission; and

    decoding the transmission using the reconfigured digital signal processor.
