<P>PROBLEM TO BE SOLVED: To provide communication device which arranges pilot signals efficiently in an OFDM signal. <P>SOLUTION: A transmitter 10 comprises: generation means 20 for generating a first OFDM symbol, a second OFDM symbol and a third OFDM symbol based on transmission data; and transmission means 30 for transmitting the OFDM symbols. When twenty nine subcarriers included in the OFDM symbols are numbered in ascending order by using integers from -14 to +14, a pilot signal is included in each subcarrier of -14th, -10th, +2nd, and +14th in the first OFDM symbol, a pilot signal is included in each subcarrier of -14th, -2nd, +10th, and +14th in the second OFDM symbol, and a pilot signal is included in each subcarrier of -14th, -6th, +6th, and +14th in the third OFDM symbol. <P>COPYRIGHT: (C)2012,JPO&INPIT |
