PROBLEM TO BE SOLVED: To allow a receiver to correct a frequency deviation even for a period when a communication opposite station transmits no signal through a communication channel in addition to a period when a communication opposite station transmits a signal through the communication channel. SOLUTION: A known symbol detection section 104 decides whether or not a received signal is transmitted, when not, an inverse spread code setting section 105 switches an inverse spread code into a spread code of a common control channel, receives the common control channel, and the known symbol extract section 106 extracts a known symbol in the communication channel or the common control channel, a phase rotation speed detection section 107 detects a phase rotation speed of the known symbol and an AFC 108 conducts automatic frequency control. |
