Abstract
The present invention calculates an echo profile on the basis of: a complex baseband signal generated in a front end () on the basis of a received signal transmitted by an antenna (); and a transmission symbol estimated value (dfin) supplied by a trellis decoder (). With the estimated transmission symbol (dfin) as a filter input, the echo profile is calculated on the basis of a filter coefficient of an adaptive filter having a received signal as the desired filter-output signal. On the basis of the calculated echo profile, a sampling-frequency control unit () controls the sampling frequency of the baseband signal in the front end (). As a result, it is possible to perform a highly accurate timing-recovery control.
