| 摘 要： | 综合运用变步长、批处理、归一化的思想,提出一种新的频域变步长批处理自适应滤波算法,分析并仿真验证其有效性.在Matlab模拟的地波、天波污染、强窄带干扰、随机噪声的复杂环境中,该算法具有较全面的优势:高的收敛速度、快的跟踪能力、小的稳态失调,完全能够满足现代数字罗兰-C系统对地波识别和标准周期过零点识别的要求,并可推广到其他一些高噪声、强相关环境提取信号的应用中. |

| Abstract: | The block LMS algorithm is integrated with normalized LMS algorithm and variable step-size LMS algorithm,from which a new variable step-size block LMS algorithm is presented,analyzed and simulated.In the presence of useless skywave,Gauss noise and strong narrow band interference,this algorithm has comprehensive advantages: high convergence rate,fast track ability and low steady-state maladjustment,hence the groundwave identification and standard cycle zero crossing identification of modern digital Loran-C are met perfectly,and in some other similar environment the algorithm still works. |
