We propose a low-complexity frequency-domain MIMO equalization scheme combining unconstrained frequency-domain equalization with out-of-band exclusion. Long-haul strongly-coupled multi-core fiber transmission experiment shows a 73% complexity reduction with negligible performance degradation using the proposed scheme.
