L0-norm constraint normalized subband adaptive filtering algorithm: Performance development and AEC application

no code implementations • 10 Apr 2023 • Dongxu Liu, Haiquan Zhao, Yang Zhou

Limited by fixed step-size and sparsity penalty factor, the conventional sparsity-aware normalized subband adaptive filtering (NSAF) type algorithms suffer from trade-off requirements of high filtering accurateness and quicker convergence behavior for sparse system identification.

In this work, we first point out that these two characteristics are related to the degree of alignment (or disalignment) of the inverse codes with the synthetic distribution.
