Degenerate Viterbi Decoding [PDF]
IEEE Transactions on Information Theory, 2013 We present a decoding algorithm for quantum convolutional codes that finds the class of degenerate errors with the largest probability conditioned on a given error syndrome. The algorithm runs in time linear with the number of qubits. Previous decoding algorithms for quantum convolutional codes optimized the probability over individual errors instead ...

Noise Correlation-Aided Iterative Decoding for Magnetic Recording Channels
, 2006 In this paper, three noise correlation-aided iterative decoding schemes are proposed for magnetic recording channels, where the correlation is imposed by the equalizer's spectral shaping effect.

FPGA implementation of trellis decoders for linear block codes [PDF]
Advances in Radio Science, 2014 Forward error correction based on trellises has been widely adopted for convolutional codes. Because of their efficiency, they have also gained a lot of interest from a theoretic and algorithm point of view for the decoding of block codes.

Node Synchronization for the Viterbi Decoder [PDF]
IEEE Transactions on Communications, 1984 Motivated by the needs of NASA's Voyager 2 mission, in this paper we describe an algorithm which detects and corrects losses of node synchronization in convolutionally encoded data. This algorithm, which would be implemented as a hardware device external to a Viterbi decoder, makes statistical decisions about node synch based on the hard-quantized ...
