【摘要】A reduced‐complexity sequence detection algorithm for Multi‐h CPM signals based on tilted phase combined with ei‐genvalue decomposition (EVD) and state‐space partitioning (SSP) was proposed to solve the complexity‐reducing problem .The optimal low‐rank approximation was achieved through the eigenvalue decomposition of the signal correlation matrix .A reduced‐states trellis was formed through classifying and fusing states and decision feedback was introduced to restrain the states transi‐tion .In this way ,the number of filter and states was reduced .Results of analysis and simulation show that the algorithm can re‐duce the number of match filters and trellis states sharply with low cost .For ARTM CPM ,it can cut the amount of match filters and states down to 3/64 and 1/8 of the original respectively with 0.2 dB loss when the error probability is 10-5 .%针对多调制指数连续相位调制全状态序列检测复杂度较高的问题，提出一种基于倾斜相位、特征值分解和状态空间分类的M ulti‐h CPM低复杂度序列检测算法。利用特征值分解获得信号降秩表示，将信号状态进行分类融合，得到减少状态网格，引入判决反馈进行状态转移约束，实现匹配滤波器和状态数的减少。给出最大似然序列检测误码性能下界并进行仿真实验，实验结果表明，以ARTM
