PURPOSE:To execute the proper alternative processing of a control channel against various forms of disturbances by employing plural disturbance detection means using different parameters respectively so as to execute the detection of whether or not the control channel is subjected to disturbance in matching with the disturbance reception state. CONSTITUTION:The 1st disturbance detection means 4 and the 2nd disturbance detection means 6 use different parameters respectively so as to detect whether or not the control channel received by a reception means 1 is subjected to disturbance by employing different parameters respectively. A 2nd control channel alternative means 5 and a 3rd control channel deputy means 7 are started by the 1st disturbance detection means 4 and the 2nd disturbance detection means 6 detecting it that the received control channel is subjected to disturbance and the active control channel is transited to a alternative control channel according to a prescribed processing. Thus, the proper alternative processing for control channels is executed corresponding to disturbances of various forms. |
