摘要
通过对观测样本进行非线形变换,对最大似然调制分类算法进行了修正,提出了一种最大似然数字调制分类算法。该算法有效消除了载波相位对最大似然算法性能的影响。理论分析和仿真结果均证明了算法的正确性和有效性。
By the non-linear transformation to the observation sample and modifying the maximum likelihood modulation classification algorithm,a maximum likelihood digital modulation classification algorithm is presented.The effect of carrier phase on the performance of the maximum likelihood classification algorithm is eliminated by the transformation.The efficiency of the proposed modified classification algorithm is verified via theoretical analysis and extensive simulations.
