Abstract

Robust signal processing algorithms rely on integer ordered statistics. This means that such algorithms cannot be used in a fuzzy environment where variables have fuzzy ranks. In this paper, we show how to calculate the k th order statistic for a set of arguments with fuzzy rank and thereby use classical robust signal processing algorithms in a fuzzy environment. The papcr concludes with a simple application of using the fuzzy k th ordercd statistic to filtering a noisy signal.
