Time delay is divided into at least two subzones according to cross-correlation values of the transmission signal and the received signal, and time delay estimation is performed on each path in each subzone respectively, thereby efficiently improving resolution of the time delay estimation. And in performing time delay estimation on each path in each subzone, cross-correlation values of other subzones are set to be predefined values, so as to lower influence of strong paths of other subzones on the time delay estimation on each path in the current subzone, thereby efficiently improving accuracy of time delay estimation of weak paths."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multipath time delay estimation apparatus and method and receiver","description":"Embodiments of the present disclosure provide a multipath time delay estimation apparatus and method and a receiver.
