RECEPTION DEVICE AND RADIO QUALITY CALCULATION METHOD

摘要

A reception device (10) calculates a radio quality in a downlink by using a plurality of pilot symbols transmitted from a base station (20).  The reception device (10) includes a correlation calculation unit (12) and a radio quality calculation unit (14).  The correlation calculation unit (12) calculates a correlation value between a first pilot symbol and a second pilot symbol on a time axis or a correlation value therebetween on a frequency axis.  If the correlation value obtained by the correlation calculation unit (12) exceeds a predetermined threshold value, the radio quality calculation unit (14) calculates a radio quality in the downlink by using a reception quality of the first pilot symbol and a reception quality of the second pilot symbol.
