Abstract
A receiver for digital information transmitted over a dispersive channel. Where the channel has a storage depth of n bits, memory requirements for an adaptive equalizer are reduced by storing transition states for only 2.sup.n' states, where n'<n, and storing at least n previous bits for 2.sup.n' states in a memory path register. At the same time the equalizer may be based on a reduced state model with 2.sup.n' states. Only n' bits are determined directly by state transitions; the remaining n-n' bits appear from each memory path leading to the respective state, stored in the memory path register.
