摘要：

We consider the problem of detecting a linear stationary non-Gaussian signal in additive Gaussian noise. Detection is assumed to be done in two steps: first a selected set of sample cumulants and/or moments of the data is computed; next a detection statistic based on these sample moments/cumulants is evaluated. Three types of detectors are considered: a likelihood ratio (optimal) detector, a weighted energy detector and a simple energy detector. The paper provides asymptotic performance analysis of these detectors for MA and ARMA signal and noise models. A simple example is worked out in detail.
