Abstract: Provided is a reception apparatus including: a correction unit that corrects phase compensation for each one of multiple phase-compensated segments that are connected one after another, in which the correction unit includes a timing generation unit that, based on a phase of a known signal, generates a timing at which an amount of the phase compensation is initialized, an amount-of-correction generation unit that, based on the phase of the known signal, generates an amount of correction for correcting the amount of the phase compensation, and a phase correction unit that performs phase correction on the phase compensation using the amount of the correction that is generated by the amount-of-correction generation unit.

Abstract: The present technique relates to a demodulation device, a demodulation method and a program capable of realizing a demodulation process at a rate equivalent to a case where I and Q channel signals are not inverted, even when the I and Q channel signals are inverted. A frequency correction unit establishes synchronization of a frequency and clock based on a signal from a frequency synchronization unit. A channel inversion detection unit of a frame synchronization unit detects presence or absence of inversion of I and Q channel signals, and supplies, as a detection result, a channel inversion detection result to the channel inversion control unit. The channel inversion control unit switches the I and Q channel signals if the inversion has occurred, based on the channel inversion detection result. This technique can be applied to a demodulation device.
