摘要
通信信号的调制方式识别是信号处理领域的重要组成部分。针对卫星信道中常用的几种数字调相信号,提出了一种基于高阶累积量和星座图的调制方式识别算法。仿真结果表明,所研究的调制方式识别算法是可行的、有效的,而且具有良好的性能。
Modulation type recognition of communication signals is an important part in the field of intercepted signal process- ing. In this paper, a new algorithm based on high-order cumulants and constellation diagram is proposed to recognize several digi- tal modulated signals used in satellite channel. Emulation indicates that the algorithm studied in this paper is feasible and effective and the performance of the algorithms is good.
