Yes, but the same is true for pure AM modulation. If you sample
and track the carrier digitally, then you get quite a bit of
processing gain due to the long integration time. My point is that
the WWVB BPSK modulation does not give (much of) an advantage
over the AM modulation because the amount of known information
is so low.... That is, unless I miss something and there is actually
an advantage that can be exploited.
