Claim Text:
1. A receiver to be used under an environment in which a phase slip or a phase fluctuation occurs, for receiving, as a received signal, a transmission signal comprising a signal formed of a plurality of pilot sequences as a part thereof and subjected to modulation after error correction coding, the receiver comprising: a phase compensation unit that uses a Markov model to model a state in which the phase slip occurs and performs demodulation for the received signal while maintaining synchronization thereof; and an error correction decoding unit that performs decoding processing for received data that has been subjected to the demodulation, the receiver having a phase slip estimation processing function that estimates the phase slip by the phase compensation unit by using the plurality of pilot sequences and the Markov model, and that estimates a phase difference component by the error correction decoding unit, to thereby correct a phase of the received data.
