Modified Viterbi algorithm for a jitter-dominant 1-D2 channel

A modified Viterbi algorithm (MVA) for a jitter-dominant 1-D ² channel is proposed. The MVA is based on the Gaussian jitter assumption and has the same structure as the Viterbi detector except that a modified error metric is used to explore the data-dependent nature of jitter noise. Error rate simulations have been performed for both VA and MVA under the assumptions of Gaussian jitter and truncated Gaussian jitter. Results show that the MVA yields lower error rates than the VA. Simulation also indicates that the two detectors produce different types of error patterns
