Method for accurately simulating multi-antenna effect when wireless mobile terminal receives signals

Abstract

The invention relates to a method for accurately simulating multi-antenna effect when a wireless mobile terminal receives signals, which comprises the following steps: according to characteristics of a multi-antenna wireless mobile terminal antenna, determining spacial angular spectrum characteristic parameter values and a pore-wavelength ratio of the wireless mobile terminal antenna; according to the spacial angular spectrum characteristic parameter values and the pore-wavelength ratio, calculating a beta factor of a multi-antenna related matrix of the wireless mobile terminal; and according to the multi-antenna related matrix established by the beta factor, calculating received signals of the wireless mobile terminal by taking the multi-antenna related matrix as a part of a whole channel matrix. The method can more objectively reflect functions and performance of eUE, and provide guarantee for the development, testing and authentication of the eUE. Simultaneously, the method also has the advantages of low environmental requirements, moderate accuracy, and simpleness, convenience and easy implementation.

Description

technical field [0001] The present invention relates to a wireless mobile terminal, in particular to a method for accurately simulating the multi-antenna effect (also called multi-antenna correlation effect) when the wireless mobile terminal receives signals. Background technique [0002] With the rapid development of technologies such as mobile phones, the multi-antenna technology on the mobile terminal side has become one of the key technologies necessary in the future, for example, for the next generation of long-term evolution (LTE) mobile phone technology or WiMax mobile phone technology or TV mobile phone technology. Correspondingly, a variety of multi-antenna wireless mobile terminals have emerged, such as cellular mobile phones, WIFI mobile stations, and broadcast TV mobile receiving stations, etc. These multi-antenna wireless mobile terminals are referred to as multi-antenna terminals in this paper, denoted by eUE. [0003] When testing and certifying the performanc...
