摘　　要：将星座图运用于调制方式识别是将一般的模式识别问题转化为形状匹配问题。在原有星座图聚类识别高阶QAM信号样式的基础上,提出了模版匹配的算法来解决阶数更高时聚类计算星座点数方法失效的问题。仿真试验证明该算法计算简便、可靠性高,便于工程实现。Using constellation diagram in modulation mode recognition is to transfer general mode recognition issue into form matching issue. On basis of original constellation diagram clustering recognition high order QAM signal mode, a template matching algorithm is presented to solve invalidation issue of clustering calculating constellation points method using higher order. The simulation test results verify that this algorithm is more simple, high reliability, and convenient to be implemented in engineering.
