Abstract: Abstract In this paper, a novel shaping pulse called root better pulse in faster-than-Nyquist (FTN) system is proposed. Compared to the conventional root raised cosine pulse in FTN system with roll factor 0.1, when bit error rate (BER) is $$10^{-5}$$ 10 - 5 , the proposed root better pulse in FTN system can obtain 0.65 dB and 0.60 dB performance gain for time packing factor at 0.85 and 0.90, respectively. The theoretical average mutual information analysis and simulated BER results both show that the proposed root better pulse in FTN system is an efficient scheme.
