Median-shift sign statistics for constant signal detection in impulsive noise environment

Abstract

In this paper, we propose a new detector based on the median-shift sign. We call it the median-shift sign (MSS) detector, which is a generalization of the classical (standard) sign detector. First, we consider the asymptotic optimum median shift (MS) values and their characteristics. Next we consider the asymptotic relative efficiency (ARE) of the MSS detectors.
