Compensation for the frequency and frequency shift which is based on the speed of portable unit and the timing shift in the time pursuit loop

摘要

Method and the device which adjust the communication receiver on the basis of the speed of the radio communication device regarding base station are offered. The receiver is adjusted base station and the radio communication device (WCD) by presuming the frequency shift of the communication signal which is transmitted in between on the basis of WCD speed. Using this estimator, as explained the frequency shift of the communication signal, you can do to the communication receiver adjustment. As for adjustment to the receiver, when WCD moving in regard to base station, with WCD, and as explained the change in the frequency of the signal which is received from WCD, the fact that frequency and the time pursuit loop are adjusted is included. Perhaps the receiver in WCD, or in the network infrastructure, or it is categorized to both.
