Re: Pseudo White Noise and Seti

The reason I don’t think the “Wow” signal is that impressive is because a race advanced enough to send us a signal should have a more sophisticated way of sending it. I searched on Google the words in the title and here is one of the first articles I found:

"A Better Way to Search for ETI Signals
by Dr. Linas Vepstas <>
April 2003

A better way to search for radio signals from extra-terrestrial intelligences is to look for PRN-encoded signals. Such encoding techniques offer powerful signal-to-noise improvements, making communication far, far more practical than using unencoded radio signals. This search technique will prove practical in the coming decades as Moore's Law provides the CPU cycles needed for such a search. ETI know Moore's Law, and depend on it to become intelligible.
