RADIO TRANSMISSION DEVICE, RADIO RECEPTION DEVICE, RADIO TRANSMISSION METHOD, AND RADIO RECEPTION METHOD |
摘要 |
<p>It is possible to provide a radio reception device, a radio transmission device, a radio reception method, and a radio transmission method which can improve the channel estimation accuracy and the reception quality. The radio reception device (200) includes: reception units (203, 204) which receive a data sequence added by a reference signal for channel estimation of a spatial propagation path at a predetermined interval; demodulation units (205, 206) which demodulate the data sequence; a channel estimation unit (208) which estimates a propagation path fluctuation state according to the reference signal in the data sequence and outputs a channel estimation value obtained by interpolating or extrapolating the data sequence; and a decoding processing unit (210) which decodes the data sequence by using the interpolated or extrapolated channel estimation value.</p> |
