Asymmetrical Filtering Impairments Mitigation for Digital- Subcarrier-Multiplexing Transmissions Enabled by Multiplication-free K-State Reserved Complex MLSE

Hexun Jiang, Zhuo Wang, Chengbo Li +10

We propose a multiplication-free K-state reserved complex maximum-likelihood-sequence-estimation (MLSE) to mitigate asymmetrical filtering impairments in digital-subcarrier-multipl…
