A novel optical comparator is proposed for the novel Viterbi‐decoding scheme, and the performance of the proposed scheme with the optical comparators is analytically investigated. The net coding gain of the proposed scheme is not degraded compared with conventional scheme, and the proposed scheme could reduce the calculation steps by a factor of ∼4/5 of the conventional scheme.
