Abstract :
A new distance metric for soft-decision decoding in impulsive noise is proposed. Results reveal that soft-decoders employing Euclidean distance as a decoding metric suffer two limitations: an increase in constraint-length leads to degraded performances; secondly, their performance is poorer than hard-decoders. Both limitations are ameliorated by the proposed distance metric.
