Abstract
A CFR estimation unit estimates channel frequency characteristic on the basis of a complex baseband signal provided by a front end via a data distribution unit, and a transmission symbol estimated value provided by a trellis decoder. On the basis of the channel frequency characteristics estimated in this manner, a carrier frequency control unit performs a carrier recovery control in order to become the carrier frequency error to zero in the front end, by performing an Auto Frequency Control based on changes in the channel phase in the full band of the frequency. As a result, carrier synchronization is performed appropriate for mobile receiving, and receiving performance is improved, even in the case of a digitally modulated signal having a DC pilot component by a single carrier.
