摘要
声回波对消领域中,多通道仿射投影算法具有良好的收敛性能,但计算复杂度较高.本文在多通道仿射投影算法基础上引入“精确块”及FTF等技术,得到了精确块快速多通道投影算法.新算法收敛性能与原算法相同,而计算复杂度大大降低.
In the field of acoustic echo cancellation, multi-channel affine projection algorithm （MCAP） has fast convergence rate but big computational complexity. Based on MCAP, a block exact fast muhi-channel projection algorithm is proposed by introducing ＂block exact＂ and FTF technique. Compared with MCAP, the proposed algorithm has the same convergence rate but mueh smaller computational complexity.
