N2 - Given cumulants of a stationary, perhaps noisy, non- Gaussian r-variate moving-average, MA(q) process, we study identifiability conditions, under which the MA coefficient matrices, the input statistics, and the order q can be uniquely determined. The selection of a unique representative from the equivalence class corresponding to a given cumualant structure involves less restrictions than that corresponding to a given covariance structure. We derive two algorithms for estimating the (possibly) nonminimum-phase MA coefficient matrices.
