Interference source localization and transmit power estimation under log-normal shadowing

This paper examines the problem of estimating the average transmitted power, number and location of a multitude of sources in a wireless environment. In particular, based on measurements of the power received by sensors placed in known locations in space, a technique is developed employing the maximum likelihood criterion in order to assess the aforementioned characteristics of the transmitting sources in a shadow fading environment. In this work the estimator is described theoretically and also numerical results are presented through simulations that corroborate the theoretical claims in a scenario of practical interest.
