METHOD FOR GENERATING UNAMBIGUOUS CORRELATION FUNCTION FOR CBOC(6,1,1/11) SIGNAL BASED ON PARTIAL CORRELATION FUNCTIONS, APPARATUS FOR TRACKING CBOC SIGNALS AND SATELLITE NAVIGATION SIGNAL RECEIVER SYSTEM

摘要

A method for generating a correlation function for composite binary offset carrier (CBOC)(6,1,1/11) signals according to the present invention comprises the following steps: generating delay signals of a signal pulse train of CBOC(6,1,1/11) modulated received signals according to phase delays; generating first to twelfth partial correlation functions by performing auto-correlation operations with the received signals and the delay signals for total time; generating a basic intermediate correlation function by performing an elimination operations with the sixth and seventh partial correlation functions; acquiring first to fifth and eighth to twelfth additional intermediate correlation functions by performing elimination operations with each of the partial correlation functions exclusive of the sixth and seventh partial correlation functions among the first to twelfth partial correlation functions and the basic intermediate correlation function; and acquiring a main correlation function by adding up the basic intermediate correlation function and the first to fifth and the eighth to twelfth additional intermediate correlation functions.
