Design and Performance Evaluation of Single Antenna SSD(Simultaneous Single Band Duplex)System Using Turbo Equalizer

摘要：

　　In this paper,we propose a single antenna SSD(simultaneous single band duplex)system using turbo equalizer.The proposed system communicates simultaneously on single band.That is the proposed system is full-duplex system.The proposed system uses balanced feed network circuit to improve isolation in single antenna structure.Also,the proposed system uses RF cancellation and digital cancellation to cancel self-interference.Additionally,the proposed system uses turbo equalizer to equalize ISI by harsh multipath fading and to collect bit errors by residual self-interference signals.By using turbo equalizer,the proposed system guarantees more QoS(quality of service).In this paper,we uses Simulink simulation program to analyze performance of the proposed system.The simulation results confirm that proposed system can communicate simultaneously by using balanced feed network,RF cancellation,digital cancellation and turbo equalizer in harsh multipath channel on single band.
