The apparatus further has a frequency domain transformer for transforming the modified CDMA signal to the frequency domain to obtain a modified CDMA spectrum and a frequency shift detector for detecting a group of candidate frequency shifts based on the modified CDMA spectrum. The apparatus further has a processing stage for processing the CDMA signal and a candidate frequency shift to obtain the time shift, when a combination of the CDMA signal, the CDMA code and the candidate frequency shift fulfills an optimization criterion and for selecting the candidate frequency shift as the frequency shift."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for estimating a frequency shift and a time shift","description":"An apparatus for estimating a frequency shift and a time shift in a CDMA signal based on a CDMA code associated with a CDMA signal, having a modulation removal stage for removing a data modulation fro","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462616","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.
