基带预失真技术是解决调制器输出信号出现的幅度失真和群时延失真的有效方法。对于全数字高速调制器的升采样、软件无线电和中频数模转换器(DAC)等特点,传统的码元间隔滤波和分数间隔滤波结构难以取得很好的效果。针对这一问题,提出了... 基带预失真技术是解决调制器输出信号出现的幅度失真和群时延失真的有效方法。对于全数字高速调制器的升采样、软件无线电和中频数模转换器(DAC)等特点,传统的码元间隔滤波和分数间隔滤波结构难以取得很好的效果。针对这一问题,提出了一种新的任意均分间隔的滤波结构,跳过重采样,直接对升采样后的数据做自适应滤波,可以获得更好的预失真效果。Matlab仿真得到的任意均分间隔滤波结构效果好于码元间隔滤波结构,且实测结果表明该结构可以显著减少高速调制器输出信号的失真。 展开更多

In this paper, we utilized the Jaulent-Miodek equation which is one of important models in particle physics and engineering. The exact traveling wave solutions for this equation “involving parameters” according to two different techniques are constructed. When these parameters are taken as special values, the solitary wave solutions are derived from it. A comparison between the obtained results using these two different methods with that obtained by previous authors is demonstrated. 展开更多

A new technique of integral representations in Cn, which is different from the well-known Henkin technique, is given. By means of this new technique, a new integral formula for smooth functions and a new integral representation of solutions of the -equations on strictly pseudoconvex domains in Cn are obtained. These new formulas are simpler than the classical ones, especially the solutions of the -equations admit simple uniform estimates. Moreover, this new technique can be further applied to arbitrary bounded domains in Cn so that all corresponding formulas are simplified. 展开更多
