摘要
为了提高滤波器权系数收敛到真值的速度,提出了一种新的有约束条件的自适应时延估计方法,约束条件是让滤波器的权系数的平方和为1。仿真结果表明,新方法收敛到时延真实值的速度快于传统方法。
To improve convergence speed of filter weight toward true value, a new explicit LMSTDE method is proposed. The constraint is that sum of square of filter weight is one. The simulation results indicate that the new algorithm has a faster convergence speed than the traditional method.
