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.

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...
