摘要 针对通信中的回声抵消,介绍了一种简化的仿射投影算法,通过对仿射投影的简化,减小了算法复杂度,并对算法进行了鲁棒性设计,提高了算法的抗干扰能力和对近端语音的鲁棒性。仿真表明,算法在保持APA算法的收敛速度和信道跟踪能力的同时,具有较高的稳定性和可靠性。 The simplified affine projection algorithm is proposed to solve echo problem in telecommunication. The algorithm can reduce the complexity and also be designed for robustness which improves the ability against impulse noise and near voice disturbance. Simulations demonstrate that the proposed algorithm is more stable and credible than the classic one, and has fast convergence and tracking speed.
