Abstract

In this paper, we propose a simultaneous single band duplex (SSD) system with turbo equalizer for full-duplex over harsh ISI channel. The proposed system uses RF cancellation and digital cancellation to cancel self-interference caused by SSD communication. Also, using turbo equalizer, the proposed system equalizes signal after digital cancellation. In this paper, we design SSD system with turbo equalizer. And then we evaluate BER performance of the proposed system comparison with SSD system with adaptive equalizer. We use Simulink program to confirm BER performance of the proposed system. The simulation results shows that the proposed system equalizes received signal effectively over harsh ISI channel and BER performance of the proposed system is better than BER performance of SSD system with adaptive equalizer.
