摘要

PPROBLEM TO BE SOLVED: To improve an SIR decision error rate. PSOLUTION: The SIR measuring instrument is provided with a receiving part 10 for receiving a signal (a), a hardness deciding part 12 for deciding the hardness of each signal point (b), a signal point average value calculating part 14 for calculating the average value of the respective signal points (c), a signal point selecting part 16 for desired signal power calculation for selecting a signal point to be used for desired signal power calculation (d), a desired signal power calculating part 18 for calculating a desired signal power (e), a desired signal power average value calculating part 20 for calculating the average value of the desired signal power (f), a signal point selecting part 22 for interference signal power calculation for selecting a signal point to be used for calculating interference signal power (g), an interference signal power calculating part 24 for calculating the interference signal power (h), an interference signal power average value calculating part 26 for calculating the average value of the interference signal power (i), and an SIR calculating part 28 for finding an SIR by calculating the ratio of the desired signal power average value and the interference signal power average value (j).
