I first ran into them for planetary missions. An LFSR has a -0
autocorrelation everywhere but within half-a-bit of synchronized, and
which point it ramps up to a huge autocorrelation when exactly
synchronized.
That's interesting. True of all LFSRs, or just maximal ones? And by
"-0" do you mean "roughly zero" (true of approximately all
pseudorandom sequences) or "exactly 0"?
Because the output of the minimal LFSR (0->0->0...) always has maximal
positive autocorrelation, waving my hands wildly I'd think it should be
true of only maximal LFSRs.
"-0" meant negative but very small -- the longer the period, the
smaller it gets.

send it privately on purpose?)
