摘要/Abstract

摘要：

递增式和扩散式仿射投影算法收敛较快,但在脉冲噪声环境下这两种分布式估计算法收敛性较差或容易发散.本文采用受网络节点的权值向量更新约束的后验误差向量?₁范数最小化方法,提出了两种抗脉冲干扰的分布式估计算法,即递增式和扩散式仿射投影符号算法.仿真结果表明,与分布式仿射投影算法相比,分布式仿射投影符号算法在脉冲噪声环境下具有更好的鲁棒性.

Abstract:

While the incremental and diffusion affine projection algorithms have fast convergence rate,they may suffer from bad convergence performance or divergence in impulsive interference environments. Based on the method of minimization of the ?₁-norm of the a posteriori error vectors subject to a constraint on the update of the weight vectors of nodes in the network,two distributed estimation algorithms against impulsive interferences are proposed,namely,the incremental and diffusion affine projection sign algorithms. Simulation results show that the distributed affine projection sign algorithms exhibit better robustness than the distributed affine projection algorithms in impulsive interference environments.
