Abstract

The invention discloses a channel modeling method of a user equipment double-antenna, which comprises the following steps: taking a user equipment double-antenna electromagnetic system comprising scatters as a three-port network comprising two way ports and a filed port, and determining channel transmission parameters of the filed port to each way ports; obtaining S parameters between the two way ports and load reflection parameters of the two way ports; according to the channel transmission parameters, the scattering parameters of the filed port, source equivalent voltage, and the reflection coefficient parameters of the field port and an excitation source, determining the coupling coefficients of the field port and the space channel; according to the coupling coefficients of the field port and the space channel, the S parameters between the two way ports, the load reflection parameters of the two way ports and the channel transmission parameters, determining the receiving power of the two way ports; and according to the receiving power of the two way ports and the source equivalent voltage, determining the channel model of the user equipment double-antenna.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for modeling a user equipment dual-antenna channel. Background technique [0002] At present, the channel models adopted by 3GPP and Winner (for example, SCM, SCME) are all quasi-physical models, because the physical space position of the scatterers in this model is uncertain. Therefore, the channel modeling method is mainly based on the Scattering statistical information of exit / incident plane village wave of the scatterer defined by end. Although the obtained channel model can theoretically support antenna elements and arrays of arbitrary topological structures, in practical applications, the standardized channel model only considers an idealized uniform linear antenna array that is out of practical use. (ULA) model. Using the uniform linear antenna array model to evaluate the performance of multi-antenna systems will lead to large deviations, which cannot meet the ...
