This work proposes a new family of cumulant-based inverse filter criteria J/sub M,m/, which require a single slice of Mth-order (M/spl ges/3) cumulants, a (2m)th-order cumulant, and a (2M-2m)th-order cumulant of the inverse filter output where 1/spl les/m/spl les/M-1, for deconvolution of linear time invariant (LTI) nonminimum phase systems with only non-Gaussian output measurements contaminated by Gaussian noise. Some simulation results are then presented for a performance comparison of the proposed criteria, Tugnait's (1993) criteria, and Chi and Kung's (1992) criteria. Finally, conclusions are presented.
