Abstract

Official abstract text for this publication.

A method for demodulating a signal is provided. The method includes: acquiring a reference clock signal provided by a power management unit (PMU) in a mobile terminal; determining a moving velocity of the mobile terminal; determining, based on the moving velocity, a Doppler frequency shift value generated when the mobile terminal receives a radio frequency (RF) signal transmitted by a base station; and demodulating, according to the reference clock signal and the Doppler frequency shift value, the received RF signal.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for demodulating a signal, comprising: acquiring a reference clock signal provided by a power management unit (PMU) in a mobile terminal; determining a moving velocity of the mobile terminal; determining, based on the moving velocity, a Doppler frequency shift value generated when the mobile terminal receives a radio frequency (RF) signal transmitted by a base station; and demodulating, according to the reference clock signal and the Doppler f…
