Sv. Schell et Wa. Gardner, BLIND ADAPTIVE SPATIOTEMPORAL FILTERING FOR WIDE-BAND CYCLOSTATIONARYSIGNALS, IEEE transactions on signal processing, 41(5), 1993, pp. 1961-1964
An algorithm that blindly adapts spatiotemporal filters to extract fro
m sensor array data one or more desired signals having known cyclostat
ionarity properties is presented. It can perform well without knowledg
e of a training signal, spatiotemporal characteristics of the interfer
ence and noise, the directions of arrival of the desired signal(s), or
any array calibration data.
