发明名称 Improved measurement of frequency difference between a transmitter and a receiver in a mobile communication system
摘要 <p>1. A frequency difference measuring method, comprising: calculating phase change values of a demodulated signal on the basis of a predetermined sample interval; and determining an average frequency difference value between a transmission frequency and a reception frequency on the basis of the calculated phase change values. 2. The method of claim 1, wherein the predetermined sample interval corresponds to the number of calculated phase change values. 3. The method of claim 2, wherein, no sample is repeated for the predetermined sample interval. 4. The method of claim 1, wherein the average frequency difference value is determined by averaging frequency difference values corresponding to the calculated phase change values and determining an obtained average value as an average frequency difference value between the transmission frequency and the reception frequency. 5. A frequency difference measuring method in a mobile communication system for determining a difference value between a transmission frequency and a reception frequency, comprising: demodulating a receiving signal; extracting a phase component of the demodulated signal; calculating phase change values of the extracted phase component on the basis of a predetermined sample interval; measuring frequency difference values corresponding to the calculated phase change values; and</p>
