Study of Sparsity-Aware Subband Adaptive Filtering Algorithms with Adjustable Penalties

16 Oct 2018Y. YuH. ZhaoR. C. de Lamare

We propose two sparsity-aware normalized subband adaptive filter (NSAF) algorithms by using the gradient descent method to minimize a combination of the original NSAF cost function and the l1-norm penalty function on the filter coefficients. This l1-norm penalty exploits the sparsity of a system in the coefficients update formulation, thus improving the performance when identifying sparse systems... (read more)
