| 摘 要： | 把三阶累积量和粒子群优化器应用于立体声回波消除.首先,把三阶累积量误差用作调整自适应滤波器系数的准则而提出了一个新的代价函数;然后,通过利用改进的粒子群优化器来优化新的代价函数而获得了一个用于立体声回波消除的累积量域自适应滤波算法.模拟结果显示:利用三阶累积量和粒子群优化器的立体声回波消除算法是可行和有效的,并有好的收敛性能.

| Abstract: | In this paper,third order cumulant and particle swarm optimizer are applied to stereophonic acoustic echo cancellation.A new cost function is first proposed,in which the cumulant error is used as the criterion to adjust the adaptive filter coefficients.Then,a cumulant domain adaptive filtering algorithm applied to stereophonic acoustic echo cancellation is presented by minimizing the cost function using an improved adaptive particle swarm optimizer.Simulation results demonstrate that it is feasible and effe... |
