Abstract
A method of generating an unambiguous correlation function for a TMBOC(6,1,4/33) signal, an apparatus for tracking a TMBOC signal, and a satellite navigation signal receiver system using the same are disclosed herein. The method of generating a correlation function for a TMBOC(6,1,4/33) signal includes generating a delayed signal delayed based on a phase delay with respect to the signal pulse train of a TMBOC(6,1,4/33)-modulated received signal; generating BOC(1,1) partial correlation functions and BOC(6,1) partial correlation functions by performing an auto-correlation operation on the received signal and the delayed signal with respect to the total time; generating a BOC(1,1) sub-correlation function; obtaining a first intermediate correlation function, obtaining second to eleventh intermediate correlation functions, and generating the BOC(6,1) sub-correlation function by summing all the first to eleventh intermediate correlation functions; and generating a main correlation function by combining the BOC(1,1) and BOC(6,1) sub-correlation functions.
