Abstract
A memoryof a pilot processing circuitholds in advance a pilot sequence converted into a frequency region signal obtained by subjecting a pilot signal symbol transmitted in one block to Ntx_p-point DFT. The pilot sequence held in the memoryis subjected to a series of processes including a roll-off filtering by a roll-off filter circuit, subcarrier mapping process by subcarrier mapping circuit, an Ndft_p-point IDFT operation by an IDFT circuit, and a cyclic prefix adding process by a cyclic prefix adding circuit
