The first communication device generates respective steering matrices for use in communicating with the respective second communication devices, including generating each steering matrix to project to a null-space of a space spanned by channel estimate matrices corresponding to others of the second communication devices. The first communication device utilizes the respective steering matrices to simultaneously transmit respective signals to the respective second communication devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Beamsteering in a spatial division multiple access (SDMA) system","description":"In a communication network, a first communication device obtains respective channel estimate matrices of respective communication channels between i) the first communication device and ii) respective ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10530457","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.
