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.
