摘要： 在基于包传输的自适应调制系统中,提出了一种新的调制方式分类的算法,即利用接收到的包数据在星座图上的每一个点周围区域的分布概率来确定调制方式,并通过分析对该算法参数的选择进行了讨论,仿真和分析结果表明此算法对自适应调制系统是非常有效的,且复杂度很低,适用于实时处理.

关键词: 自适应调制, 盲检测, 调制分类

Abstract: In this paper, a novel blind modulation classification algorithm is proposed in adaptive modulation on a packet-by-packet basis. This algorithm makes use of the distribution probability of the surrounding region of each point in the constellation vector. Analysis and simulation results show that it can achieve optimal performance in adaptive modulation and its complexity is very low and is suitable for real time processing.

Key words: adaptive modulation, modulation classification, blind detection
