水和水蒸汽作为一种重要工质,在电站热能动力工程上有着广泛的应用。德、俄、英、加等7国12位科学家组成的联合研究小组提出了一个全新水和水蒸汽计算公式,在1997年德国Erlanger召开的水和水蒸汽性质国际联合会(IAP WS)上通过并发表,称为IAPWS-IF97公式。根据IF97的文档，自己编写的C代码

详细表述了分数阶傅立叶变换的离散实现，将现有的算法进行比较。-In this note we make a critical comparison of some matlab programs for the digital computation of the fractional Fourier transform that are freely available and we describe our own implementation that lters the best out of the existing ones. Two types of transforms are considered: First the fast approximate fractional Fourier transform algorithm for which two algorithms are available. The method is described in H.M. Ozaktas, M.A. Kutay, and G. Bozdagi. Digital computation of the fractional Fourier transform. IEEE Trans. Signal Process., 44:2141{2150, 1996. There are two implementations: one is written by A.M. Kutay the other is part of package written by J. O Neill. Secondly the discrete fractional Fourier transform algorithm described in the master thesis C . Candan. The discrete fractional Fourier transform, Bilkent Univ., 1998 and an algorithm described by S.C. Pei, M.H. Yeh, and C.C Tseng: Digital fractional Fourier transform base

非线性放大器对发射信号的影响，与调制方式密切相关。不同的调制方式，所得到的时域波形是不同的，如用于欧洲移动通信的GSM制式，该制式采用了高斯滤波的最小偏移键控（GMSK），是一种相位平滑变化的恒定包络的调制方式，因此可以用非线性放大器来放大，不存在包络失真问题，也不会因为频谱再生而干扰邻近信道。 -Non-linear amplifier on the transmit signal of the impact is closely related with the modulation method. Different modulation methods, the resulting time-domain waveforms are different, such as for the European GSM mobile communications standard, the standard use of Gaussian minimum shift keying filter (GMSK), is a smooth change in the phase constant envelope modulation, so you can use non-linear amplifier to amplify, there is no envelope distortion, nor because of spectral regrowth and adjacent-channel interference.
