Abstract

The invention discloses a channel modeling method and a channel modeling device of a mobile terminal double-antenna. The method comprises the following steps of: determining channel transmission parameters according to a voltage gain directional diagram; determining a coupling coefficient between a field port representing the push-pull effect of a double-antenna source and a channel according to the channel transmission parameters, a scattering parameter and a reflection coefficient parameter; determining the near-field effect between double antennae according to an S parameter between two circuit ports, and determining the coupling relation between the two circuit ports and an external circuit according to the reflection coefficient parameter; determining a b matrix according to the coupling coefficient, the source reflection coefficient parameter, the s parameter and load reflection coefficient parameters of the two circuit ports; and calculating to obtain the receiving power of the two circuit ports according to the b matrix, the coupling coefficient and the channel transmission parameters from the field port to the two circuit ports. The method and the device can provide guarantee for property research, test and authentication of the double-antenna mobile terminal and have the advantages of low requirement on environment, moderate precision, convenience and feasibility at the same time.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for modeling a mobile terminal 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, and the channel modeling method is only based on the scattering near the two ends of the channel. The outgoing / incoming wave direction (DOD / DOA) information of the volume. Theoretically speaking, 3GPP's SCM can support antenna arrays with any topological structure, but at present, in the modeling scheme of SCM / SCME / WIM and the specific implementation scheme of winner, only the uniform linear antenna array (ULA), which is the most optimal Direct, simplest antenna model. [0003] Due to the high performance pursued by B3G and 4G systems, the new generation antennas are requ...
