摘要
在对脉冲成形幅相调制信号模型与通信系统中各种环节加解扰所发挥的不同作用简要概述的基础上,针对脉冲成形幅相调制这一类信号,将比特级加扰操作推广至符号级广义加扰,建立了符号级广义加扰与解扰的理论模型,阐述了其工程实现方法,并对相关特性进行了详细分析。最后,通过示例性仿真展示了符号级广义加扰在脉冲成形幅相调制信号传输中所发挥的作用,从而为推广其在通信电子防御中的工程化应用提供了重要参考。
Based on a brief overview of the pulse-shaping amplitude-phase modulated signal model and the different roles played by scrambling and descrambling in various parts in communication systems,for such signals as pulse-shaped amplitude-phase modulation,the bit-level scrambling operation is extended to symbol-level generalized scrambling,a theoretical model of symbol-level generalized scrambling and descrambling is established,its engineering implementation method is described,and the relevant features are analyzed in detail.Finally,an example simulation indicates the role of symbol-level generalized scrambling and descrambling in pulse-shaping amplitude-phase modulated signals transmission,which provides an important reference for the popularized engineering application in communication electronic defense.
