Abstract
Official abstract text for this publication.
Methods and apparatus for wireless communication, in a mobile device, that includes receiving a signal from a network and obtaining pruned autocorrelation for specific channel delays of the received signal. Aspects of the methods and apparatus include determining pruned autocorrelation properties of the received signal. Aspects of the methods and apparatus also include comparing the pruned autocorrelation properties of the received signal against a reference threshold. Aspects of the methods and apparatus also include verifying that the received signal is a valid signal for WCMDA processing.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of wireless communication, comprising: receiving a signal from a network; obtaining an autocorrelation of the received signal, wherein the autocorrelation indicates correlation of the received signal with a delayed signal for each of a plurality of delays; obtaining a pruned autocorrelation of the received signal for a channel delay spread wherein correlations due to delays less than the channel delay spread are removed from the autocorrelation;…
