It is pointed out that an effective search for extraterrestrial intelligence (SETI) presents a signal processing task with unusual requirements. In the first place, algorithms with a very low false alarm probability are needed. This implies, that the interpretation of noise as a signal must be rare. Secondly in a SETI, attention must be given to signals having narrow-band or pulsed features. Theoretical considerations are discussed along with aspects of pulse detector motivation, independent pulse trains and the false alarm rate, and software considerations.
