This paper presents a comparative analysis of the multiplexing principles, allowing increasing the technical efficiency of radio resource usage based on the three-dimensional signals spatial separation in a spherical coordinate system. These methods allow creating spatial multichannel communications between certain points (areas) of the space through the radiators and signal processing system of wireless base station. Three-dimensional spatial selectivity in spatial matched filtration is provided by the physical processes of the focusing and the differentiation signals by their front curvature, and in the spatial correlation signal processing – by orthogonality of spreading sequences, their reusing by cyclic shift and synchronization, depending on the distance from the base to the mobile station.
