【摘要】 CPM是一种非线性调制技术,常用的线性盲均衡算法难以直接用来对该类信号进行有效的均衡.本文通过分析传统常模准则用于CPM信号盲均衡时存在的问题,提出一种适合于全响应CPM信号的线性盲均衡与调制指数盲估计的联合算法.该算法在使用线性均衡器对CPM信号进行均衡的同时,可以对未知调制指数进行准确的估计.算法的性能在计算机仿真实验中得到验证.更多还原

【Abstract】 Continuous-phase modulated(CPM)signals,as nonlinear modulation schemes,can’t be equalized directly by usual linearblind equalizers. In this paper, based on the analysis of solutions to the traditional CM criterion with input of CPM signals, a joint al-gorithm is proposed for blind equalization and modulation index estimation of full-response CPM signals. The new algorithm can sim-ultaneously achieve blind equalization of channel and estimation of unknown modulation index. Simulation results illustrate the per-formance of the proposed algorithm.更多还原
