| Resumen | We consider the problem of detecting a known signal with constant magnitude immersed in noise of unknown variance,when the propagation channel is frequency-flat and randomlytime-varying within the observation window. A Basis ExpansionModel with random coefficients is used for the channel, and a Generalized Likelihood Ratio approach is adopted in order to cope with deterministic nuisance parameters. The resulting scheme can be seen as a generalization of the well-knownMatched Filter detector, to which it reduces for timeinvariantchannels. Closed-form analytical expressions are provided for the distribution of the test statistic under both hypotheses, which allow to assess the detection performance. |
