<p><P>PROBLEM TO BE SOLVED: To provide the wireless receiver which detects whether the interference from an adjacent channel signal is the interference from an adjacent channel on the low frequency side or on the high frequency side when an OFDM wireless signal performing frequency hopping is received. <P>SOLUTION: A means 6 for calculating the received signal quality calculates the received signal quality of a plurality of pilot signals where the position in each OFDM symbol using each band becomes constant on the frequency axis for each band, and with regard to a band including a pilot signal having the received signal quality thus calculated which is less than a threshold, a section 7 for detecting adjacent channel interference detects the interference from an adjacent channel on the high frequency side if a pilot signal having the received signal quality less than the threshold exists on the high frequency side, and detects the interference from an adjacent channel on the low frequency side if a pilot signal having the received signal quality less than the threshold exists on the low frequency side. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
