Scatterer Localization Using Large-Scale Antenna Arrays Based on a Spherical Wave-Front Parametric Model.

In this contribution, an algorithm based on the space-alternating generalized expectation-maximization principle is proposed for estimating the locations of scatterers involved in the last-hops of propagation paths when a large-scale antenna array is used in a receiver for channel measurement. The underlying generic parametric model is constructed under the spherical wave-front assumption, which a...
