    Abstract: Cumulant (higher-order statistics) based inverse filter criteria maximizing Jr,m=|Cm|r/|Cr| m, where m≠r and Cm (Cr) denotes the mth-order (rth-order) cumulant of the inverse filter output, have been proposed for blind deconvolution and equalization with only non-Gaussian output measurements of an unknown linear time-invariant (LTI) system. This paper shows that the maximum of Jr,m associated with the true inverse filter of the unknown LTI system, exists only for r to be even and m>r, otherwise, Jr,m is unbounded. The admissible values for (r,m)=(2s,l+s) where l>s⩾1 include (2,3), (2,4) and (4,6) proposed by Tugnait (see IEEE Trans. Signal Processing, vol.41, no.11, p.3196-3199, 1993), Wiggins (1978), and Shalvi and Weinstein (see IEEE Trans. Information Theory, vol.36, p.312-321, 1990) in addition to more new ones such as (2,5), (2,6) and (4,5). Some simulation results for the inverse filter criteria Jr,m with the proposed admissible values of (r,m) are then provided. Finally, we draw some conclusions
