A receiving unit receives a light signal that is transmitted from the transmitting unit to demodulate the received light signal to a signal on a plurality of LED channels basis. By determining performance information on a plurality of LED channels basis by estimating a state on the plurality of LED channels basis, the receiving unit feeds back the performance information to the transmitting unit, and the transmitting unit determines a modulation degree on the channel basis according to performance information on a channel basis of the plurality of LEDs that are fed back from the receiving unit and performs modulation on the plurality of LED channels basis of the plurality of data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Visible light communication system, system data modulation method therefor, and performance information feedback method","description":"A visible light communication system, and a method of modulating data and a method of feeding back performance information in the system, are provided.In the system, a transmitting unit modulates a pl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621267","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.
