In one example, a receiving device includes a plurality of receive antennas for receiving communication information, a memory for storing the communication information, and one or more processors for processing the communication information. The one or more processors are configured to receive, through a wireless communication channel, a pilot signal transmitted by a transmitting device, determine, based on the received pilot signal, channel state feedback comprising a quantized representation of the pilot signal as received at the receiving device, and send, through the wireless communication."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel tracking and transmit beamforming with frugal feedback","description":"In general, this disclosure describes techniques for beamforming using limited feedback that exploit the spatio-temporal channel correlation and avoid the limitations of codebook-based feedback and Ma","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9647745","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.
