wherein:
Ns comprises a count of matched filters of the matched filter set;
n comprises an index of a matched filter within the matched filter set;
i comprises a sample index for n;
sT( . . . ) comprises a template signal at a selected time;
TS comprises a duration of a sample interval of the template signal;
