采用Fortran语言的正交曲线网格生成程序-Fortran language, the use of orthogonal curvilinear grid generation process

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.
