本文提出了一项特别适用于进行实时信号处理、可作为评估自适应算法性能的新指标——收敛时间。然后依据此指标,提出了一种简化的块变步长(SBVS)自适应算法,并导出了它的频域实现。计算机模拟结果表明,该算法在性能上优于BLMS 算法。
This paper presents a new metric that is particularly suitable for real-time signal processing as a measure of the performance of adaptive algorithms - the convergence time. Then based on this index, a simplified SBVS adaptive algorithm is proposed and its frequency domain implementation is derived. Computer simulation results show that the algorithm is superior to BLMS algorithm in performance.
