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

Abstract

The invention discloses a modeling method of a multi-antenna channel antenna branch power ratio and a modeling apparatus thereof. The modeling method comprises the following steps: determining descriptive parameters of the incident characteristic and scattering characteristic of a field port; determining descriptive parameters of the transmission characteristic and reflection characteristic of a line port; determining descriptive models of transmission characteristic and coupling characteristic of the filed port and the line port; and determining a descriptive model of a multi-antenna channel antenna branch power ratio. According to the invention, the research, test and authentication on the multi-antenna performance of a mobile terminal are guaranteed.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a modeling method and device for multi-antenna channel antenna branch power ratios. 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 DOD / Direction of Arrival (DOA) information of the scatterers near the two ends of the channel. From the concept As mentioned above, 3GPP's SCM can support antenna arrays of any topology, but SCM / SCME / WIM only considers Uniform Linear Array (Uniform Linear Array, referred to as ULA) is the most direct and simplest antenna model. [0003] The high performance pursued by Beyond third Ge...
