wave envelope meaning in Chinese
波包络线
波浪包络线
Examples
- By theory and practice simulation , the several types of constant envelope modulation techniques are analyzed and compared , including theirs modulation principle , phase path , the modulated wave envelope , power spectrums , error bit rate and the influence of its power spectrums of the band - limited and non - linear , etc . especially we have researched the ijf - oqpsk modulation technique , and the performance of its inter - symbol interference and time jitter free , and its strongly resisting of spectral spreading
结合理论和实验仿真结果，分析讨论了卫星通信中的各种恒包络调制技术，对它们的调制原理，相位路径，已调波包络，功率谱密度，误码性能，以及带限非线性信道对其功率谱的影响等方面都作了研究和比较。特别研究了ijf ? oqpsk在消除码间干扰和定时抖动方面的性能及其优良的旁瓣特性和抑制频谱扩展特性。 - We transformed the nonlinear equation of the light - wave envelope in lossy dispersion - managed optical fibers and obtained numerical curve of the equation with the use of mathematical software , then the approximate solution was found by fitting of the curve , also the envelope propagation of the quasi - soliton was analysed
摘要对有损耗的色散光纤中光波包络的非线性方程进行变换，借助数学软件得到非线性方程的数值曲线，并通过对曲线的拟合得到方程的近似解，对色散管理类明孤子的传输进行了分析。
