Maximal Capacity Partial Response Signaling

Abstract

In this paper we investigate partial response signaling (PRS) systems that are intended to operate close to capacity. We show that finding PRS systems with maximal capacity is a rather easy optimization task. We give an alternate way of defining bandwidth for PRS systems based on capacity considerations; this differs considerably from the traditional method based on transmission power. Practical PRS schemes are derived, based on these ideas. Their bit error rate is significantly better than earlier, distance-optimizing schemes.
