Low-Complexity Feature Stochastic Gradient Algorithm for Block-Lowpass Systems
New approaches have been proposed to detect and exploit sparsity in adaptive systems. However, the sparsity is not always explicit among the system coefficients, thus requiring some tools to reveal it. By means of the so-called feature function, we propose the low-complexity feature stochastic gradi...
