A. Gatherer et P. Papamichalis, Scattered lookahead without finding polynomial roots or solving simultaneous equations, IEEE SIGNAL, 47(9), 1999, pp. 2415-2418
In this paper, we describe a method of calculating scattered lookahead coef
ficients that leads to a simple closed-form expression for the scattered lo
okahead filters. The coefficients are then found by simple polynomial multi
plication. We also give closed-form expressions for any recursive decomposi
tion of scattered lookahead.
