A method embodiment includes forming, using a precoding matrix generated in accordance with channel conditions, a plurality of beams for a plurality of transmit signals and a plurality of self-interference cancellation signals corresponding to the plurality of transmit signals. The method further includes transmitting, at a plurality of antennas, the plurality of beams for the transmit signals, and receiving, via the plurality of antennas, a plurality of receive signals. A corresponding self-interference cancellation signal is then added to each of the plurality of receive signals to obtain a plurality of corrected receive signals, and the plurality of corrected receive signals are detected at a plurality of receivers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for multiple-input and multiple-output (MIMO) full-duplex precoding structures","description":"Embodiments are provided to enable effective cancellation or reduction of the self-interference (SI) introduced when applying full-duplex (FD) transmission to Multiple-Input-Multiple-Output (MIMO) sys","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9608706","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.
