Mobile communication system, and base transceiver station apparatus and mobile station apparatus used in mobile communication system
Abstract:
A phase error detector in a base transceiver station detects a phase error caused by a Doppler shift in a received wave from a mobile station. A phase rotator rotates a phase of a transmission symbol in a base band region so as to cancel the Doppler shift, which occurs in a downlink from a base transceiver station to a mobile station based on the phase error detected by the phase error detector.
