摘要:
针对多径环境下的麦克风阵列直达波方向估计问题,该文研究了一种基于多通道互关联的二阶统计量自适应盲辨识算法。算法采用稳健无约束的归一化最小均方误差自适应滤波器来盲估阵元间的直达波时延参数,消除了现有同类技术的恒模约束。理论推导和计算机仿真证明了该算法在多径条件下的有效性。
Abstract:
Based on the multi-channel cross-relation,an adaptive second-order statistics blind identification algorithm is presented to estimate the direction of the direct wave for a microphone array in the multipath environment.To eliminate the constant modulus constraint on the weight vectors inherited in existing similar methods,the robust and unconstrained normalized-least-mean-squares adaptive filter is utilized to blindly estimate the time delay parameter of the direct wave between array elements.The effectiveness of the algorithm under the conditions of multipath is verified by theoretical analysis and simulation results.
