An apparatus for measuring SIR, based on a plurality of symbols obtained from received signals, includes a first unit which controls an averaged-symbol number in accordance with measured SIR, a second unit which calculates signal power, based on the averaged-symbol number of symbols, a third unit which calculates interference power, based on the averaged-symbol number of symbols, and a divider which divides the signal power by the interference power. For instance, the first unit includes a table including correspondence between SIR regions each of which is associated with each SIR, and an averaged-symbol number suitable for measuring each of the SIR regions, and a fourth unit which retrieves the table with the measured SIR to detect an averaged-number symbol associated with SIR region including the measure SIR. |
