RECEPTION DEVICE, RADIO DEVICE AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a technique for suppressing increase of the probability of communication failure while suppressing increase of the circuit scale when a plurality of frequency channels are used.SOLUTION: A measuring unit 52 executes a measurement of the intensity of a reception signal at a first frequency channel and a measurement of the intensity of a reception signal at a second frequency channel different from the first frequency channel while performing switching between the measurements. When the intensity of the reception signal which is measured in the measuring unit 52 and is the intensity of the reception signal at one of the first frequency channel and the second frequency channel is not less than a threshold value, a detector 54 performs detection processing of a preamble to be included in the reception signal. in the one frequency channels.SELECTED DRAWING: Figure 4
