摘要 利用通信信号的循环平稳特性,通过对QAM信号高阶循环累积量的研究,提出了一种基于高阶循环累积量的星形和方形QAM载波估计算法。并且对该算法进行了理论分析,仿真结果证明,该算法的正确性和有效性。 An algorithm based on higher-order cyclic cumulants for the estimation of SQAM and MQAM carrier frequency is proposed. The algorithm utilizes the cyclostationary property of communication signals and the higher-order cyclic cumulants of QAM signals. The theory of this algorithm is analyzed. The efficiency of the proposed esti- mation algorithm is verified via Matlab simulations.
