In TV relay stations for SFN(Signal Frequency Network), it is a proble that the coupling between transmitting antenna and receiving antenna may cause distortion and oscillation. To study a possibility of suppressing the couplin, we have developed Coupling Wave Canceler for DQPSK-OFDM using adaptive signal processing techinique. Experiments and computer simulations are carried out on the performance of the canceler. The canceler can reduce BER at a CN ratio of 18dB from the order of 10<-2> to 10<-6>.
