In this paper, we consider the design of multi-resolution non-coherent multiple-input multiple-output (MIMO) systems that enable Unequal Error Protection (UEP). A method for designing multi-layer non-coherent Grassmannian constellations is introduced. Specifically, the proposed method yields multi-layer constellations that are amenable to a natural set partitioning strategy. The resulting subsets...
In this work, a multiple-target tracking problem for a Wi-Fi through wall system is formulated and a new Direction Of Arrival (DOA) angle estimation technique is investigated to solve the tracking problem in the presence of clutter. The DOA estimation from objects behind walls is investigated utilizing the MUltiple SIgnal Classification (MUSIC) algorithm compensated by Extended Kalman Particle Filtering...
In this paper, we develop a geometry-inspired methodology for generating systematic and structured Grassmannian constellations with large cardinalities. In the proposed methodology we begin with a small close-to-optimal “parent” Grassmann constellation. Each point in this constellation is augmented with a number of “children” points, which are generated along a set of geodesics emanating from that...
