IC and Signal Detection based on LSTM for FTN Signaling-based Digital Twin Synchronization System in Multipath Channel

This paper proposes interference cancellation and signal detection technology for digital twin synchronization system based on FTN signaling in multipath channel. The digital twin synchronization system executes synchronization between physical objects and digital world objects. Therefore, high-speed communication is important for real time synchronization. In this paper, FTN signaling is considered for high speed digital twin synchronization system. Although the FTN signaling can give high spectral efficiency, it cannot avoid ISI generation. To reduce the interference and detect the transmitted symbols, this paper proposes LSTM-based IC and signal detection technique. The proposed technique can provide better performance than that of BCJR algorithm in multipath channel.
