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 \(10^{-5}\), 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.

比奈奎斯特系统更快的新型整形脉冲

在本文中,提出了一种在快于奈奎斯特(FTN)系统中称为根更好脉冲的新型整形脉冲。与滚动因子为 0.1 的 FTN 系统中传统的根升余弦脉冲相比,当误码率 (BER) 为\(10^{-5}\)时,提出的 FTN 系统中的根更好脉冲可以获得 0.65 dB 和 0.60 dB时间打包因子的性能增益分别为 0.85 和 0.90。理论平均互信息分析和模拟误码率结果均表明,提出的FTN系统中根更好脉冲是一种有效的方案。
