| Abstract: | UMP-Invariant detection of signal in noise with unknown level is discussed in this paper. The structure of UMP-Invariant detector is derived for detecting known signal waveform in Gaussian noise with unknown level. Numerical calculations are carried out for the properties of this detector and some valuable results are obtained. |
