Abstract

A digital spread spectrum communication system calculates phase and frequency error (119) on a received signal from a communicating entity during a wireless communication and pre-corrects a signal for phase and frequency error prior to transmission to that entity. Moreover, a carrier offset correction (149) is performed, either at a chip, or at a symbol level.
