Robust joint erasure marking viterbi algorithm decoder

摘要

Joint erasure marking Viterbi algorithm (JEVA), decoder schemes, methods, and systems are provided which perform robust trellis decoder techniques. The provided JEVA decoding schemes are shown to be maximum likelihood decoding schemes that find the most likely transmitted code sequence with a set of symbol erasures, without knowledge of the impulsive noise probability distribution function, and can be implemented sequentially such that they are well suited for dynamically changing impulsive noise channels. In addition, the disclosed details enable various refinements and modifications according to decoder and system design considerations. For example, truncated JEVA is provided for continuous transmission and long frame applications.
