Convergence Behavior and Convergence Rates of Stack Filters

چکیده
The four direrent types of stack filters, type-0 through type-3, are determined by four dfferent shapes of the on-set of the positive Boolean function from which the stack filter is constructed. Under all three appending strategies commonly considered in the literature --first and last value carry on strategy, constant value carry on strategy, and the circular approach -stack filters of type-0 through type-2 possess the convergence property, while type-3 stack filters do not all share this property. Examples of cyclic behavior in type-3 stack filters are given. The rates of convergence for stack filters of type-I and type-2 are determined for each appending approach.

Convergence Behavior and Root Signal Sets of Stack Filters*
The four different types of stack filters, type-0 through type-3, are determined by four different shapes of the on-set of the positive Boolean function from which the stack filter is constructed. Under all three appending strategies commonly considered in the literature---first and last value carry-on strategy, constant value carry-on strategy, and the circular approach--stack filters of type-...
متن کاملCONNECTING T AND LATTICE-VALUED CONVERGENCES
$top$-filters can be used to define $top$-convergence spaces in the lattice-valued context. Connections between $top$-convergence spaces and lattice-valued convergence spaces are given. Regularity of a $top$-convergence space has recently been defined and studied by Fang and Yue. An equivalent characterization is given in the present work in terms of convergence of closures of $top$-filters. M...
متن کاملA NOTE ON STRATIFIED LM-FILTERS
We develop a theory of stratified $LM$-filters which generalizes the theory of stratified $L$-filters. Our stratification condition explicitly depends on a suitable mapping between the lattices $L$ and $M$. If $L$ and $M$ are identical and the mapping is the identity mapping, then we obtain the theory of stratified $L$-filters. Based on the stratified $LM$-filters, a general theory of lattice-v...
متن کاملStratified (L; M)-semiuniform convergence tower spaces
The notion of stratified (L, M)-semiuniform convergence tower spaces is introduced, which extends the notions ofprobabilistic semiuniform convergence spaces and lattice-valued semiuniform convergence spaces. The resulting categoryis shown to be a strong topological universe. Besides, the relations between our category and that of stratified (L, M)-filter tower spaces are studied.
متن کاملSpeech Enhancement by Modified Convex Combination of Fractional Adaptive Filtering
This paper presents new adaptive filtering techniques used in speech enhancement system. Adaptive filtering schemes are subjected to different trade-offs regarding their steady-state misadjustment, speed of convergence, and tracking performance. Fractional Least-Mean-Square (FLMS) is a new adaptive algorithm which has better performance than the conventional LMS algorithm. Normalization of LMS ...
