A scheme of fast blind equalization of multipath channels using antenna arrays is proposed. An array of antennas is used along with a fractionally spaced equalization structure to combine with temporal and spatial diversities. Necessary and sufficient conditions of channel (blind) identifiability are presented. The proposed approach offers fast equalization by exploiting cyclostationary properties of the observation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
