In a relay station of SFN (Single Frequency Networks) for DTB (Digital Terrestrial Broadcasting), a coupling effect between transmitting antenna and receiving antenna should be reduced to an allowable level in order to avoid distortion and oscillation problem. Therefore, we have already made a basic report of the coupling canceler using reference signals such as SP (Scattered Pilot) contained in QAM-OFDM signals. In this paper, we propose a method of calculating transfer function of the coupling paths for the PSK-OFDM modulation schemes without SP, and applied the proposal method to the coupling canceler on some computer simulations. The simulations have shown the usefulness of the proposed method.
