Modeling method and device for relevance of multi-antenna differential polarization channels

Abstract

The invention discloses a modeling method and a modeling device for the relevance of multi-antenna differential polarization channels. A multi-antenna electromagnetic system is used as a three-port microwave network comprising two circuit ports and one field port. The method comprises the following steps of: determining an incidence feature characterization parameter and a dispersion feature characterization parameter of the field port; determining a transmission feature characterization parameter and a reflection feature characterization parameter of each of the circuit ports; determining transmission feature characterization parameters and coupling feature characterization parameters of the field port and the circuit port; and determining a characterization model of the relevance of the multi-antenna differential polarization channels. By the invention, the problem that no modeling scheme for the relevance of the multi-antenna differential polarization channels is provided at present can be solved; therefore, guarantee is provided for performance research, test and authentication of a plurality of antennas of a mobile terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a modeling method and device for multi-antenna heteropolarized channel correlation. Background technique [0002] At present, the channel model (Special Channel Model, referred to as SCM; Special Channel Model Enhanced, referred to as SCME) adopted by the 3rd Generation Partnership Project (3GPP) and the WINNER (Wireless World Initiative New Radio) project team ), both are quasi-physical models, because the physical space position of the scatterer in this model is uncertain, and the channel modeling method is only based on the outgoing wave direction DOD / incident wave direction (Direction of Arrival , referred to as DOA) information. Conceptually, 3GPP's SCM can support antenna arrays of any topology, but SCM / SCME / WIM only considers the Uniform Linear Array (Uniform Linear Array) in its more detailed modeling scheme and WINNER's specific implementation scheme. , referred to as...

Problems solved by technology

[0005] The miniaturization and high-density characteristics of the multi-antenna of the mobile terminal determine the effective representation of the correlation of the multi-antenna heteropolarized channel of the terminal. However, the inventors found that there is no modeling scheme for the correlation of the heteropolarized channel of the mobile terminal.
