| 摘 要： | 针对背景噪声中多个复正弦信号的提取问题,提出利用二阶陷波器复数算法的级联来实现,并给出了一种自适应级联算法.基于对软件复杂度和计算量的考虑,在这种算法的基础上又给出一种改进的二阶自适应陷波器级联的复数算法,大大降低了系统复杂度和计算量.仿真实验表明,两种陷波器级联算法均能很好地提取背景噪声中的复正弦信号,并准确估计复正弦信号的频率. |

| Abstract: | This paper mainly discusses the realization of the cascaded structure based on two-ordered IIR notch filter,aims at retrieving the multiple complex sinusoids immerging in background noise.A cascaded structure is proposed,but it has a lot computation,so a improved cascaded structure is proposed.The new cascaded structure can largely reduce the complexity of the system.The results of computer simulation are shown which confirm that the two cascaded structure can detect complex sinusoids in noise and at the sa... |
