| 摘 要： | 针对最小均方误差(LMS)算法的自适应谱线增强器收敛速度慢的缺点,将快速横向滤波(FTF)算法的自适应谱线增强器应用于罗兰-C信号中随机噪声的抑制。经过仿真验证,结果表明,FTF算法自适应谱线增强器具有收敛速度快,输出均方误差小的优点,能够克服LMS算法的不足,用来抑制罗兰-C信号中的随机噪声是可行的。

| Abstract: | Because of the slow convergence rate of the adaptive line enhancer based on the LMS(least mean square) algorithm,the adaptive line enhancer based on the FTF(fast transversal filter) algorithm are used in the Loran-C signal processing to filter the random noise.The result of the simulation shows that the adaptive line enhancer based on the FTF algorithm has the advantages of quick convergence and less mean square error,and could get over the shortcomings of LMS algorithm.It's feasible to use the adaptive lin... |
