two adjacent correlators that both lead the transmitted hop on time point is equal to the correlator spacing interval dsi divided by the transmitted hop interval thi for the case where the spacing interval is u00bd of the hop interval the difference in these two coefficients is 0 5 assuming the on time point resides between correlators n and n 1 then correlators n and n u2212 1 are both leading the on time point and s can be calculated using h n u2212 h n u2212 1 c n s k u2212 c n u2212 1 s k s can then be solved for by substituting 0 5 for c n u2212 c n u2212 1 and rewriting the equation as similarly the sum for c for two adjacent correlators that span the on time point is equal to two minus the dsi divided by the thi for the case where the spacing interval is u00bd of the hop interval the sum of these two coefficients is 1 5 again assuming the on time point resides between correlator n and n 1 then k can be calculated using h n h n 1 c n s k c n 1 s k h n h n 1 c n c n 1 s 2 k k can then be solved for by substituting 1 5 for c n c n 1 and rewriting the equation as c n can now be calculated for correlator h n using the established values for s and k once c n has been determined the following calculation gives an estimate of the amount of time time error that correlator h n leads the on time point by when the transmitted on.
