Abstract
A communication device includes a signal determiner determining whether there is a reception signal, and a period estimator estimating an interruption period of interruption of a signal transmitted from a device as a source of the reception signal, using a determination result from the signal determiner. The period estimator includes a differential operator calculating a differential value of the determination result, a masking operator calculating a provisional period of the interruption period using the differential value, controlling use of the differential value and provisional period based on internal state, and outputting the provisional period to be used, a period calculator calculating the interruption period using the provisional period, a signal existing section calculator calculating a signal existing section using the provisional period, a periodic timing estimator estimating periodic timing using the provisional period and signal existing section, and a state determiner determining the internal state using the interruption period.
