Abstract
This correspondence describes three new algorithms for finite impulse response system identification from output measurements, using fourth- order cumulants. The impulse response is assumed to be complex, and th e input-a complex i.i.d. non-Gaussian sequence. The algorithms are bas ed on a certain low-rank matrix constructed from the output cumulants. An application of the algorithms to blind equalization of digital com munication channels is discussed and illustrated by some examples.
