<P>PROBLEM TO BE SOLVED: To provide a receiving apparatus and interference power estimating method in which, even if a correlation of phasing variation between reference signals is low, interference power estimation is performed highly accurately to determine accurate receiving quality. <P>SOLUTION: The interference power estimating method includes: receiving a signal including a plurality of reference signals being discontinuous on a time-frequency plane; extracting the reference signals from the received signal; linearly combining channel variation values determined from reference signals surrounding a specific time-frequency reference signal on the time-frequency plane, respectively, with predetermined weighting; and using a linear combination value, which is obtained by the linear combination, to estimate interference power. <P>COPYRIGHT: (C)2011,JPO&INPIT |
