Minimax phase error design of allpass variable fractional-delay digital filters by iterative weighted least-squares method In this paper, an iterative weighted least-squares (LS) method is proposed for the design of allpass variable fractional-delay (VFD) digital filters, so th... JJ Shyu,SC ...
Let () be the system of all subgroups A() are not minimax Z-modules. The author studies -modules such that () satisfies the minimal condition as an ordered set. It is proved that a locally soluble group with these conditions is soluble. The structure of the group is described.关键词:...
In the second term, we first introduce an overlapping group sparsity fractional-order total variation regularizer to eliminate staircase artifacts while preserving structural information. Then, we adopt the minimax-concave penalty to further accurately estimate the image edges. Finally, we employ...
To address this problem, a periodic group-sparse method based on a generalized minimax-concave penalty function is proposed in this paper. This method uses periodic group sparse techniques to capture the periodic clustering trends of fault impact signals. To further enhance the sparsity of the ...
