Title:
RECEPTION DEVICE AND TRANSMISSION/RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/143410
Kind Code:
A1
Abstract:
The present invention achieves a reception device that can improve reception performance for data signals and control signals. The present invention is provided with: a control signal transmission path estimation unit (205) that uses a pilot signal extracted from a reception signal to estimate the transmission path of a control signal and that generates a first transmission path estimated value; a control signal FDE unit (206) that uses the first transmission path estimated value to perform frequency domain equalization processing on the control signal; a control signal demodulation unit (209) that demodulates the post-equalization control signal; a control signal encoding unit (211) that encodes the demodulated post-equalization control signal; an FFT unit (212) that generates a control signal replica from the encoded post-equalization control signal; a data transmission path estimation unit (213) that uses the control signal replica and the first transmission path estimated value to estimate the transmission path of a data signal; and a data FDE unit (215) that uses a second transmission path estimated value to perform frequency domain equalization processing on the data signal.
