Single carrier transmission system, communication device, and single carrier transmission method using for them

摘要

A memory 21 of a pilot processing circuit 2 holds 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 memory 21 is subjected to a series of processes including a roll-off filtering by a roll-off filter circuit 22, subcarrier mapping process by subcarrier mapping circuit 23, an Ndft_p-point IDFT operation by an IDFT circuit 24, and a cyclic prefix adding process by a cyclic prefix adding circuit 25.
