Abstract: PROBLEM TO BE SOLVED: To prevent the generation of phase deviation in a timing reproduction signal (pilot tone) when a sequence shifts from training to normal data communication. SOLUTION: In a digital subscriber line transmission, transmission is switched in time sharing between outgoing data transmission from a station side apparatus to a subscriber side apparatus and incoming data transmission from the subscriber side apparatus to the station side apparatus to perform transmission by a single line, data of one symbol is divided, carrier frequencies having different frequency for each divided data are modulated and frequency-multiplexed, and the data are transmitted by some symbols. The phase difference between a training symbol 501 and a transmission symbol except cyclic prefix CP at the time of normal transmission is made into an integer multiple of a pilot tone period, and training processing and normal data communication processing are executed syncrhonously with the pilot tone signal.
