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 co-polarization channel correlation of the terminal multi-antenna. However, the inventors found that there is no modeling scheme for the co-polarization channel correlation of the mobile terminal.

Abstract

The invention discloses a modeling method of multi-antenna copolarization channel correlation and an apparatus thereof. A multi-antenna electromagnetic system is regarded as a three port microwave network which comprises two road ports and one field port. The method includes the following steps: determining property characterization parameters of incident and scattering of the field port; determining property characterization parameters of transmission and reflection of the road ports; determining property characterization models of transmission and coupling of field and road ports; determining a characterization model of multi-antenna copolarization channel correlation. The method discloses a modeling scheme of mobile terminal copolarization channel correlation, wherein the modeling scheme has not provided yet. Therefore, performance research, test and authentication of multiple antennas of mobile terminals can be guaranteed by the method.

Description

technical field [0001] The present invention relates to the communication field, in particular to a modeling method and device for multi-antenna co-polarization 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...
