<p><P>PROBLEM TO BE SOLVED: To provide a transmitter for transmitting a signal in a multi-carrier system, based on a frame structure. <P>SOLUTION: Each frame includes at least two signal patterns mutually approaching in a frequency direction, and at least two data patterns. The transmitter has: a signal mapping means 57 for mapping signal data onto each frequency carrier of at least the two signal patterns having the same length each in the frame; data mapping means 58, 58', 58'' for mapping data onto the frequency carrier of at least the two data patterns in the frame; a conversion means 60 for converting the signal and data patterns to a time domain from a frequency one to generate a transmission signal of the time domain; and a transmission means 61 for transmitting the transmission signal of the time domain. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
