This paper deals with blind identification and deconvolution algorithm for an arbitrary, possibly white or colored, stationaryor nonstationary signal, which is observed through array sensors. By using multiple sensors with their individual outputs sampled at arate 1/T, one can obtain cyclostationary signals. They can be considered as a single-input multiple-output model with an identical butunknown input signal. With the array measurement, an algorithm for estimating the system transfer function model and its parametersis presented.
