  • Reception device, receiving method, and program
    Patent number: 10389393
    Abstract: The present technology relates to a reception device, a receiving method, and a program capable of improving a reception state. A delay wave by multipath is estimated on the basis of sensor information detected by a sensor unit, a replica of the delay wave is generated by a sum of products of a coefficient for each delay wave and a signal of a reception wave according to delay time on the basis of the estimated delay wave by the multipath, and the generated replica of the delay wave is subtracted from the signal of the reception wave, thereby removing the delay wave from the signal of the reception wave. The present technology may be applied to a receiver which receives a broadcast wave.
