The source (or sender) broadcasts random network coded symbols with hierarchical modulation to the relays and the destination (or receiver). In following time slots, the relays, which have successfully decoded the original packet, transmit additional random network coded symbols to the destination. By applying the present disclosure into a multi-hop relay consumer device network, which comprises a set of consumer devices, error free transmission with high efficiency can be achieved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Symbol-level random network coded cooperation with hierarchical modulation in relay communication","description":"Disclosed is a novel cooperative communication strategy jointly using symbol-level random network coding and hierarchical modulation in order to effectively minimize packet error rate in error prone w","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8516344","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.
