Abstract
Official abstract text for this publication.
A method of generating a correlation function for a CBOC(6,1,1/11) signal includes generating a first correlation function by performing a first elimination operation on a first and twelfth partial correlation function pair of 12 partial correlation functions, generating a fourth correlation function by performing a first elimination operation between second and third correlation functions that are generated by performing a second elimination operation between two difference functions between sixth and seventh partial correlation functions and the first correlation function, and generating a main correlation function by summing resulting waveforms that are generated by performing a first elimination operation between each of the 12 partial correlation functions and the fourth correlation function or by performing a first elimination operation between each of the remaining 8 partial correlation functions, excluding first, sixth, seventh and twelfth partial correlation functions from the 12 partial correlation functions, and the fourth correlation function.
First claim
Opening claim text (preview).
What is claimed is: 1. A delay locked loop (DLL), comprising: a local signal generation unit configured to generate an early and late delayed signal pair r(t+τ+Δ/2) and r(t+τ−Δ/2), early and late delayed, respectively, based on a phase delay τ and a delay value difference, with respect to a signal pulse train of a composite binary offset carrier (CBOC)(6,1,1/11)-modulated received signal r(t); early and late autocorrelation units configured to generate first to twelfth early par…
