Modulation tiers are generated at a subcarrier group level such that network elements can use different profile tiers depending in the subcarrier group in use. A scheduler facilitates the scheduling of modulation tiers for network element destination groups across subcarrier groups, where the modulation tier for a network element may vary between subcarrier groups. The scheduler also facilitates scheduling multiple network element destination groups for transmission of a plurality of subcarrier groups for optimal transmission to the network elements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for selecting modulation tiers for transmissions over an orthogonal frequency division multiplexed (OFDM) channel","description":"With the introduction of orthogonal frequency division multiplexing (OFDM) technology to communication channels in a cable network, cable modems that receive data downstream over subcarriers of the OF","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9647801","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.
