Communication apparatus, demodulation apparatus, carrier reproduction apparatus, phase error compensation apparatus, phase error compensation method, and storage medium on which phase error compensation program has been stored
[Problem] To enable a large-capacity, high-quality data communication that is excellent in bit error rate characteristic even in an adverse noise environment mainly caused by phase noises or thermal noises. [Solution] Included are: a first phase error detection filter that generates, on the basis of a forward sequence of received symbols, a first phase difference value and a first phase error estimated value; a second phase error detection filter that generates, on the basis of a backward sequence of received symbols, a second phase difference value and a second phase error estimated value; a phase error combination means that generates a third phase error estimated value on the basis of the first and second phase error estimated values and one of the first and second phase difference values; and a phase error compensation means that compensates the phase error of the received symbols in accordance with the third phase error estimated value.
