| Abstract: | Signals corrupted by deterministic interference and white Gaussian noise are common in various engineering applications. In this letter we propose a non-data-aided algorithm for joint measurement of the interference level and the noise power. The algorithm applies an iterative approach based on the maximum likelihood criterion. |

| Keywords: | The maximum likelihood criterion Joint measurement Deterministic interference White Gaussian noise |
