METHOD FOR GENERATING UNAMBIGUOUS CORRELATION FUNCTION FOR TMBOC(6,1,4/33) SIGNAL BASED ON EQUALLY SPLIT PARTIAL CORRELATION FUNCTIONS, APPARATUS FOR TRACKING TMBOC SIGNALS AND SATELLITE NAVIGATION SIGNAL RECEIVER SYSTEM
A method for generating a correlation function of a TMBOC(6,1,4/33) according to the present invention comprises the following steps of: generating a delayed signal delayed by phase delay with regard to a signal pulse train of a TMBOC(6,1,4/33) modulated received signal; generating 12 partial correlation functions by performing an autocorrelation operation for a received signal and the delayed signal over total time T (0=t=T); generating a sub-correlation function by performing an eliminating operation for sixth and seventh partial correlation functions; and generating a main correlation function by adding results of eliminating operations for each of the 12 partial correlation function or each of 10 partial correlation functions excluding the sixth and seventh partial correlation functions and the sub-correlation function, wherein the eliminating operation can be defined as the following algebraic equations: A+B-A-B=0 if AB=0, or A+B-A-B0 if AB0, where A and B are real numbers.
