Embodiment approach
[0048] figure 1 It is a block diagram showing the configuration of the receiving device according to the embodiment. The reception device 100 includes an antenna 101 , a tuner unit 102 , a synchronization unit 103 , an FFT unit 104 , an equalization unit 110 , and a channel characteristic estimation unit 111 .
[0049] The antenna 101 receives a multi-carrier transmission signal transmitted from a transmission station not shown.
[0050] The tuner unit 102 selects a signal of a desired channel from the multi-carrier transmission signal received by the antenna 101, performs frequency conversion, and outputs it as a received signal.
[0051] The synchronization unit 103 estimates signal timing and the like based on the received signal output from the tuner unit 102 , and notifies the FFT unit 104 of the estimated signal timing and the like.
[0052] The FFT unit 104 converts the reception signal in the time domain (time domain) output from the synchronization unit 103 into a ...
