摘要： The present technique relates to a receiving device, a receiving method, and a program that are designed to improve reception performance. A receiving device according to one aspect of the present technique includes: a gain control unit that adjusts the power of a signal including a first pilot signal transmitted as signals having a high correlation in terms of polar direction via different transmission channels, and a second pilot signal transmitted as signals having a low correlation in terms of polar direction via the different transmission channels; and a control unit that controls the followability of the gain at the gain control unit in accordance with a data transmission method. The present technique can be applied to a receiver that receives data transmitted by MISO (Multi Input, Single Output) compliant with the DVB-T2 standards.

摘要： Disclosed herein is a signal processing apparatus including a processing block configured to perform a carrier shift amount detection process for detecting a carrier shift amount constituting a carrier error used for demodulating an orthogonal frequency division multiplexing signal known as the OFDM signal; and a correction block configured to correct the OFDM signal in accordance with the carrier shift amount. The OFDM signal includes a first preamble signal including subcarriers, and a second preamble signal including subcarriers of which the spacing is narrower than the spacing of the subcarriers included in the first preamble signal. The second preamble signal includes pilot signals which are known signals located at intervals of a predetermined number of subcarriers. The processing block detects the carrier shift amount using a correlation of the subcarriers included in one such second preamble signal.
