Eigen-Inference for Multi-Source Power Estimation

International audienceThis paper introduces a new method to estimate the power transmitted by multiple signal sources, when the number of sensing devices and the available samples are sufficiently large compared to the number of sources. This work makes use of recent advances in the field of random matrix theory that prove more efficient than previous ``moment-based'' approaches to the problem of multi-source power detection. Simulations are performed which corroborate the theoretical claims
