In general, the pattern recognition part of automated SETI is very simple:
look for a single channel signal that is so far above the noise as to
be pretty unlikely to be an artefact. After that, you probably use
a much better pattern matcher than the computer - the human brain.
The only other patterns that I've seen suggested are repeating pulses
and channelised carriers. Both of these are really the same problem
and I presume both can be attacked with the fast folding algorithm
that SETI@Home now uses (they've translated the original, freely available,
source into C, from Fortran, and optimised it for the cache memory on
PCs, but the basic idea is still from the published code).
