: A two-parallel distribution matcher (DM) architecture for cost-effective probabilistic shaping, compatible with the standardized Flexible Optical Transport Network (FlexO), is proposed and optimized through a multi-step design process. It minimizes rate loss and achieves lower complexity and an 85% reduction in memory compared to FlexO LUT-based PAS implementations over AWGN channels.

Abstract
: A two-parallel distribution matcher (DM) architecture for cost-effective probabilistic shaping, compatible with the standardized Flexible Optical Transport Network (FlexO), is proposed and optimized through a multi-step design process. It minimizes rate loss and achieves lower complexity and an 85% reduction in memory compared to FlexO LUT-based PAS implementations over AWGN channels.File in questo prodotto:
