Abstract
A method of deciding whether an observed received signal is a particular signal of interest (SOI) includes the steps of: providing a statistical model of the particular signal of interest and a statistical model of the environment when the particular signal of interest is not present, and processing the observed received signal in accordance with a decision rule that uses the provided statistical models to decide whether the observed received signal is the particular signal of interest. The decision rule is: where LLR is log likelihood ratio, P denotes a probability, a(y) and a(y) are functions of first and second attributes of the observed signal y in a sequential order that said attribute functions are presented for computation of LLR(y), and +λ and −λ are real numbers, wherein the statistical model of the particular signal of interest includes functions of attributes that individually have a probability distribution function fwhen the observed received signal is the particular signal of interest such that()>0,where fis a probability distribution function of the respective individual attribute when the observed received signal is not a signal of interest.
