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

Abstract

The invention discloses a modeling method and device for the PPL (polarize power loss) of a multi-antenna channel. The method disclosed by the invention comprises the following steps: determining the characterization parameters of incident and scattering properties of a field port; determining the characterization parameters of transmission and reflection properties of a routed port; determining a characterization model of transmission and coupling properties of the field port and the routed port; and determining a characterization model of the PPL (polarize power loss) of the multi-antenna channel. The method and device disclosed by the invention provide a guarantee for the performance research, testing and certification of multiple antennas at a mobile terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multi-antenna channel polarization power loss (Polarize Power Loss, PPL for short) modeling method and device. Background technique [0002] Currently, the channel models SCM (Special Channel Model) and SCME (Special Channel Model Enhanced) adopted by the Third Generation Partnership Project (3GPP) and the WINNER (Wireless World Initiative New Radio) project team are quasi-physical models. Because the physical spatial position of the scatterers in this model is uncertain, the channel modeling method is only based on the outgoing wave direction and the incoming wave direction (Direction of Arrival (referred to as DOA)) information of the scatterers near the two ends of the channel. Conceptually In other words, 3GPP's SCM can support antenna arrays with arbitrary topological structures. However, SCM, SCME and WIM only consider Uniform Linear Array (ULA for short) in their more d...
