摘要
针对多电平信号(MPSK,QAM)提出了一种改进的Gardner时钟误差检测算法。仿真结果表明该算法能明显消除PAM/QAM信号检测中的自噪声,而且其计算复杂度很低。
A modified Gardner timing-error detecting algorithm for multi-level signal(MPSK,QAM) is proposed. The simulation results show that the algorithm can obviously eliminate the self-noisy in the detecting of PAM/QAM signals. And in practical applications, the computational complexity of such algorithm is low.
