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.

摘要： Disclosed are a receiving apparatus, a receiving method, and a program capable of shortening time taken in tuning. A broadband signal where a plurality of signals is arranged is received. Control information used to extract a predetermined signal from the broadband signal is obtained from the broadband signal. The obtained control information is stored. After the control information is stored, the stored control information is read when a predetermined signal is extracted from the broadband signal. The predetermined signal is extracted from the broadband signal based on the read control information. This technology is applicable to a receiving apparatus that receives a signal according to a DVB-C2 standard.
