Frequency information is extracted based on an observation of a single symbol carrying pilot tones, which can be at any bandwidth location. Specifically, the frequency error information is extracted after selecting tones assigned to a specific user. The frequency error can be corrected based on the estimation. Further, the disclosed aspects can be applied to multi-path environments."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency error estimation","description":"Aspects relate to frequency estimation and tracking.
