摘要
数字调制方式的识别对于通信信号分析有着重要的作用 .此文首先介绍了数字调制方式的识别算法(DMRA) ,即判决理论算法的原理 ;然后提出了一种基于该算法的判决流程 ;最后在软件环境中进行计算机仿真 ,通过实验数据对该算法进行修正 .仿真结果表明 ,该修正算法具有较高的识别率和良好的可行性 .
Identification of digital modulation schemes plays an important role in signal analysis. In this paper, the algorithm based on decision theory for the identification of digital modulation schemes is presented. A new algorithm with some revision is also introduced and implemented with computer simulation. The results are given to show the feasibility and accuracy of the algorithm.
