To that end, a time difference for each of the plurality of RF front-end circuits is determined by measuring a time difference between a reference signal (common to all of the RF front-end circuits) and the mixing signal of each RF front-end circuit. The initial phase for each output signal is then determined based on the measured time difference for the corresponding RF front-end circuit. Determining the initial phase in this manner accounts for any uncertainty of the phase when the RF front-end circuits are activated, enabling the phase of the corresponding antenna element to be accurately controlled."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Local oscillator phase synchronization for beamforming and MIMO","description":"An initial phase of each output signal generated by a plurality of radio frequency (RF) front-end circuits is determined by mixing an input signal with a mixing signal in a mixer of the corresponding ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9596040","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.
