Abstract
Systems and methods for improving the performance of decoders of forward error correcting codes use the information contained in late packet arrivals to update (or recompute) the state of the decoder. These systems and methods are generally applicable to decoders that maintain state information in decoding successive bits or information frames so as to improve the performance (i.e., the bit error rate) of the decoder since the recomputed state is exactly the state that the decoder would have had if the information contained in the late packet had originally arrived on time and been decoded in a usual manner. In effect, the updating of the decoder state following a late packet arrival terminates the propagation in time of the effect of the late packet erasure on the state of the decoder.
