Receiving method, synchronization device and receiving apparatus

A synchronization device comprising:

• a detector that detects a position of a first sequence and a position of a second sequence in a received signal of each of a plurality of channels received by a plurality of receivers;
• a calculator that calculates, for each of the plurality of channels, a time period which has been required to receive a predetermined part of the received signal, based on the detected position of the first sequence and the detected position of the second sequence;
• a correcting circuitry that performs a correcting process of correcting one or both of an outlier included in the position of the first sequence having been detected for each of the plurality of channels and an outlier included in the time period having been calculated for each of the plurality of channels;
• a Doppler estimation circuitry that estimates Doppler shift by using the time period after the correcting process for each of the plurality of channels;
• and
• an offsetting circuitry that offsets the received signal by using the Doppler shift having been estimated for each of the plurality of channels and outputs the received signal divided based on the position of the first sequence after the correcting process to an equalizer.

A receiving apparatus comprising:

• a plurality of receivers that receive signals of different individual channels;
• a detector that detects a position of a first sequence and a position of a second sequence in a received signal of each of a plurality of the channels, the received signals is each of the signals having been received by the plurality of receivers;
• a calculator that calculates, for each of the plurality of channels, a time period which has been required to receive a predetermined part of the received signal, based on the detected position of the first sequence and the detected position of the second sequence;
• a correcting circuitry that performs a correcting process of correcting one or both of an outlier included in the position of the first sequence having been detected for each of the plurality of channels and an outlier included in the time period having been calculated for each of the plurality of channels;
• a Doppler estimation circuitry that estimates Doppler shift by using the time period after the correcting process for each of the plurality of channels;
• an offsetting circuitry that offsets the received signal by using the Doppler shift having been estimated for each of the plurality of channels and outputs the received signal divided based on the position of the first sequence after the correcting process;
• and
• an equalizer that performs an equalizing process by using the received signal of each of the plurality of channels output from the offsetting circuitry.
