Abstract
Freedom for relationship between division of a signal processing unit and a pilot signal is improved in a multi-carrier communication system such as OFDM. An encoded signal is divided into resource blocks and the signals are arranged independently of the arrangement of a pilot signal. The signal arranged at the same position as the pilot signal causes a puncture upon transmission.
