| 摘 要： | 针对室内以及山区多径环境下MPSK信号的调制识别,提出一种基于高阶累积量的识别算法。该算法利用高阶累积量良好的抗噪性能,实现了多径信道下的有效识别。理论分析及仿真结果表明,采用本文所提出的识别算法,在中等信噪比条件的,对多径信道的MPSK信号的整体识别率在90%以上,能满足实际应用的需要。

| Abstract: | An algorithm based on high-order cumulant is proposed for the modulation recognition of MPSK signals under the multi-path environment of in-door and mountainous area.The good de-noising performance of high-order cumulant is utilized to obtain effective recognition under the multi-path environment.Theoretical analysis and simulation resuls show that under the medium signal to noise ratio,the overall recognition rate is above 90% by the algorithm proposed in this paper,which can meet the requirement of practi... |
