Abstract :
This paper addresses the problem of detecting the presence of multiplicative noise, when the information process can be modelled by a parametric AR process. A suboptimal detector based on higher-order cumulante (HOC) is studied. This detector consists of filtering the data by the fitted AR filter. HOC of the residual data are shown to be efficient for the detection problem.
