Abstract

The invention discloses an antenna layout structure for a concentric circle (or a coaxial circular table) uniform circular array vortex electromagnetic wave MIMO system. The structure is formed by nesting multiple uniform circular array antennas having the array element interval of lambda/2 concentrically or coaxially. The invention discloses a multi-mode vortex electromagnetic wave MIMO signal separation method suitable for the antenna in the invention; namely, channel estimation is carried out by responses of No.0 array elements of arrays in various layers; then, MIMO solution is carried out according to a channel obtained by estimation and responses of layer-by-layer array elements of the antenna; a row vector corresponding to the layer is obtained from an MIMO solution matrix; mode separation of the row vector is carried out; independent modulation information carried in a multi-mode vortex signal propagated by the antenna corresponding to the layer can be obtained; and all layers of a receiving antenna are traversed, so that the MIMO gain and the mode multiplexing gain of the antenna disclosed by the invention can be obtained. Simultaneously, the invention discloses a vortex electromagnetic wave MIMO signal separation method and an implementation device based on a concentric circle (or a coaxial circular table) uniform circular array.

Description

technical field [0001] The invention relates to a MIMO-oriented vortex electromagnetic wave signal orthogonal transformation separation method and device, and belongs to the technical fields of communication signal processing technology and radar signal processing technology. Background technique [0002] The proposal of vortex electromagnetic wave wireless communication technology was not imagined by Bo Tide et al. As early as 1992, physicists discovered vortex beams. At present, the results of information transmission based on vortex beams reported in the literature are very gratifying. [0003] On June 24, 2011, Swedish scientist Bo Tide and University of Padua Fabrizio Tamburini and others verified the ability of vortex electromagnetic waves to transmit information in Venice, Italy, opening the door to wireless communication technology based on vortex electromagnetic waves. [0004] According to the classical electrodynamic theory, the vortex electromagnetic wave is for...
