Abstract :
The decision depth Ld for finite and infinite partial response signaling (PRS) schemes is investigated. New measures are proposed that take into account error event multiplicity. We conclude that small to moderate decoder decision depths achieve performance near MLSE even for near catastrophic codes. Under some constraints, the decision depth should be an increasing function of the signal to noise ratio.
