[time-nuts] WWVB BPSK Receiver Project? (fwd)

[Bob Camp]

Hi

Could you generate a "lead" and a "lag" estimate of the signal (in addition
to your "center") and integrate against each of them on the fly? If so you
would need a *lot* less memory. I seem to recall you tried something like
this on the one of the Loran receivers. 

Bob

That would be the ideal way to do it, since it would make one heck of
a comb filter and eliminate pretty much anything else.
