Signal arranging method and a communication device

In multicarrier communication scheme such as OFDM, to reduce the deterioration of communication quality due to the influence of inter-cell interference. Data symbols to be transmitted to the pilot signal at the same time, in a data symbol is not a pilot signal at the same time, to change the alignment of the error correction encoded signal. Or changes the modulation method in the data symbols to be transmitted to the pilot signal at the same time, a data symbol is not a pilot signal at the same time. Furthermore, it is also possible to reduce the signal amplitude or power of the data symbols to be transmitted to the pilot signal at the same time.
