RADIO COMMUNICATION DEVICE, AND RECEPTION QUALITY ESTIMATING METHOD

摘要

A radio base station 1100 comprises a frequency-domain/time-domain converter 1160 for converting transfer route estimation information again into a time domain signal series or a signal series in a time domain, and a time domain SNR estimator 1170 for calculating the signal power of a radio singnal on the basis of the time domain signal series contained in a time band (ts), of the whole time domain containing the time domain signal series converted again, and for calculating a noise power on the basis of the time domain signal series contained in a time band (tn), thereby to estimate the signal-to-noise ratio of the radio signal.
