    • The present technology relates to a receiving device, a receiving method, a program, and a receiving system which may improve reception performance in the case of receiving a signal with a variable frequency band. A receiving device according to an embodiment of the present technology includes a demodulation unit configured to convert a received signal to a baseband signal in the case where a first frequency differs from a second frequency, wherein the first frequency is a center frequency in a band of the received signal, the second frequency is a center frequency in a band of a desired signal included in a part of the band of the received signal, and a DC component of the baseband signal is to be a frequency in the vicinity of the second frequency. The present technology may be applied to a receiver which receives an OFDM signal of DVB-C2.

    • 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.
    • 这里公开了一种信号处理装置,包括:处理块,被配置为执行用于检测构成用于解调称为OFDM信号的正交频分复用信号的载波误差的载波移位量的载波移位量检测处理; 以及校正块,被配置为根据载波移位量校正OFDM信号。 OFDM信号包括包括子载波的第一前导码信号和包括间隔窄于包括在第一前导信号中的子载波的间隔的子载波的第二前导码信号。 第二前导信号包括作为以预定数量的副载波间隔设置的已知信号的导频信号。 处理块使用包括在一个这样的第二前导信号中的子载波的相关性来检测载波移位量。
