Abstract. A standard way of implementing Huffman's optimal code construction algorithm is by using a sorted sequence of frequencies. Several aspects of the algorithm are inves...
In this paper, we consider improvement of parameter estimation accuracy of multicomponent polynomial-phase signals (mc-PPSs) using the product high-order ambiguity function (PHAF)...
Permutation ambiguity is an inherent limitation in independent component analysis, which is a bottleneck in frequency-domain methods of convolutive source separation. In this pape...
