Frequency-domain adaptive MIMO filter with fractional oversampling using stochastic gradient descent for long-haul transmission over coupled 4-core fibers: erratum

Abstract

This erratum corrects errors in Fig. 9(b) and Fig. 14 of our published paper [Opt. Express 31, 13104 (2023)10.1364/OE.486032]. Other results, descriptions, and conclusions are not affected by this correction.
