METHOD FOR GENERATING UNAMBIGUOUS CORRELATION FUNCTION FOR TMBOC(6,1,4/33) SIGNALS BASED ON PARTIAL CORRELATION FUNCTIONS, DEVICE FOR TRACKING TMBOC SIGNALS, AND SYSTEM FOR RECEIVING SATELLITE NAVIGATION SIGNALS USING SAME

摘要

Disclosed is a method for generating an unambiguous correlation function for TMBOC (6,1,4/33) signals based on partial correlation functions. The method includes the steps of: generating a delay signal which is delayed according to phase delay for a signal pulse train of a TMBOC (6,1,4/33) modulated receiving signal; respectively generating BOC (1,1) partial correlation functions and BOC (6,1) partial correlation functions by respectively performing autocorrelation operations of the receiving signal and the delay signal for the entire time; respectively erase operating the BOC (1,1) partial correlation functions to generate a BOC (1,1) sub-correlation function; obtaining a first middle correlation function by erase operating first and twelfth BOC (6,1) partial correlation functions among twelve BOC (6,1) partial correlation functions, obtaining second to eleventh middle correlation functions by respectively erase operating second to eleventh BOC (6,1) partial correlation functions and the first middle correlation function, and generating a BOC (6,1) sub-correlation function by summing up all first to eleventh preceding middle correlation functions; and generating a main correlation function by summing up the BOC (1,1) sub-correlation function and the BOC (6,1) sub-correlation function.;COPYRIGHT KIPO 2015
