title: Filtering-tolerant transmission by the Walsh-Hadamard transform for super-channel beyond 100 Gb/s.
abstract: Super-channel transmission is a promising solution to increase the capacity of a channel beyond 100 Gb/s in next-generation optical networks. The performance of a super-channel comprising multiple subcarriers, however, degrades if optical filtering distortions occur in particular subcarriers. In this paper, we propose a method that improves super-channel performance by dispersing the distortions over all subcarriers. We also numerically demonstrate that the method effectively mitigates the filtering-induced penalty suffered by super-channels.
