Abstract

A system for equalization of two-way digital communications between a base and portable unit is described. Equalization is implemented in a manner so as to reduce the complexity of the portable unit. The reverse link (portable to base transmission) is equalized by a decision feedback equalizer (DFE). The forward link (base to portable) is equalized by an asymmetric decision feedback equalizer (ADFE), which consists of a forward filter located at the transmitter, and a decision feedback filter at the receiver.
