The first detected calibration signal and the injected first calibration tone are then compared to produce a first comparison signal. The transmitter chain's phase and/or gain is then adjusted based on this first comparison signal. The first calibration tone located within one of the lower and upper guard bands of the communication channel of the transmitter chain."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-disruptive phased array calibration for FDD and TDD communication systems","description":"A method of calibrating a transmitter chain in a phased array system in which a lower guard band is assigned to a lower side of an operating carrier of a communication channel and an upper guard band ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11973629","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.
