| Abstract(in English) | In a low cost relay station for SFN (Single Frequency Networks) of digital terrestrial broadcasting, the coupling effect from transmitting antenna to receiving antenna should be reduced to avoid distortion and oscillation problem. In this paper, a simple booster system without decision and re-modulation technology is focused. For OFDM (Orthogonal Frequency Division Multiplexing) system, we propose a coupled wave canceling system using adaptive signal processing with small process delay time. The proposal system use adaptive FIR filter to cancel, which is controlled by transfer function determined from scattered pilot symbols obtained broadcast wave. The usefulness of the proposed system has been verified by the computer simulations. |
