With the method, apparatus or the system provided by this application, very good compensation performance may be achieved in a range of power consumption of the multicarrier optical communication system by only opening and using few taps of the compensation filter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonlinear compensation method and apparatus and system in multicarrier optical communication system","description":"A nonlinear compensation method and apparatus and a system in a multicarrier optical communication system where the method includes: determining a coefficient of a linear filter in nonlinear compensat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9774399","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
