The present paper is concerned with the adaptive cancellation of coupling wave effect in the Single Frequency Networks (SFN) relay station of the Orthogonal Frequency Division Multiplexing (OFDM) digital terrestrial broadcasting system. Due to lack of the PE condition, the coupling wave channel dynamics outside the signal bands cannot be identified precisely and that makes the stable cancellation very difficult. It is illustrated that both the estimation of the system model and the evaluation of the modeling error are important in the stable canceller design procedure.
