To increase throughput efficiency and improve performance, FTN (Faster Than Nyquist) method and LDPC (Low Density Parity Codes) codes are employed in DVB-S3 system. In this paper, we proposed efficient turbo equalization model to minimize inter symbol interference induced by FTN transmission. To make performance improved in turbo equalization model, the outputs of LDPC and BCJR (Bahl, Cocke, Jelinek and Raviv) equalizer are iteratively exchange probabilistic information. In fed LDPC outputs to extrinsic information of BCJR equalizer, we split output to separate bit probabilities. We confirmed that performance was improved compared to conventional methods as increasing throughput parameters of FTN.
