ARIA: Anti-diagonal Reduced-cost Index-masked Adaptive BLMS Algorithm
arXiv eess.SP0 views
arXiv:2611.06474v1 Announce Type: new Abstract: The block least-mean-square (BLMS) algorithm supports high-throughput adaptive filtering but incurs high computational cost as the filter length and block size increase. This letter proposes anti-diagonal reduced-cost index-masked (ARIA) adaptive BLMS, which reduces coefficient-update multiplications through anti-diagonal index masking and tap-wise step-size scaling while keeping the filtering exact. Mean-square error (MSE) analysis establishes an explicit step-size bound, and misadjustment. An extension, ARIA-MF (ARIA with masked filtering), also applies the mask during filtering; its analysis shows that the excess MSE is redistributed across block rows while its block average is approximately preserved. Simulations validate the analysis and shows very good agreement with the estimates
