Self-phase modulation of fiber does not affect the pulse shape of chaotic signal, however, its product of nonlinear phase shift can widen the chaotic signal spectrum.
结果表明：自相位调制不影响混沌信号脉冲的形状，但能产生非线性相移使混沌信号频谱展宽；
In this paper, ideal rectangle and Gaussian shape pulse act as radar echo signal model. Through simulation research, application of NMTI method in wideband radar systems is discussed in detail.
该文分别以理想矩形和高斯钟形脉冲作为雷达回波信号模型，通过仿真研究，详细讨论了NMTI方法在宽带雷达中的应用。
Thus pulse shaping technique can be used not only shape the spectrum of the transmitted signal to increase the bandwidth efficiency but also to reduce its PAPR.
因此脉冲成形技术不仅能对传输信号进行频谱成形来提高系统的频带利用率，而且还可以减小信号的PAPR值。
