The channel matrix is organized in one or more channel vectors each associated with a corresponding one of the one or more receiver antennas (221, 222, 231, 232, 241, 242). An iterative optimization algorithm is applied to determine a precoding matrix from the channel matrix. At least one step size of the iterative optimization algorithm is set depending on a vector norm of at least one of the channel vectors. Multi-antenna transmission by the transmitter device (210) is then controlled based on the determined precoding matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel-matrix dependent step size for iterative precoding matrix calculation","description":"A channel matrix representing characteristics of a multi-path channel between a transmitter device (210) equipped with multiple transmitter antennas (211, 212, 213, 214, 215) and at least one receiver","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11962372","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.
