The performance assessment of a novel multilevel modulation format based on partial-response signalling called absolute added correlative coding (AACC) by numerical simulations is delineated, targeting short-range and interconnect high-speed optical networks. The spectral efficiency, chromatic dispersion tolerance and receiver sensitivity of 4-instensity level AACC are discussed and compared against other well-known existing modulation formats, namely, non-return-to-zero on-off keying and 4-ary pulse-amplitude modulation (4-PAM). The robustness of the higher order of AACC over 8-PAM and 16-PAM is also discussed.
