Problems solved by technology

Although the concept of multi-antenna correlation matrix has been proposed at present, no one has proposed what kind of multi-antenna correlation matrix should be used to accurately simulate the multi-antenna effect in a certain terminal and wireless channel environment to be simulated. corresponding solution
If the simulation of multi-antenna effects cannot be accurately realized, it will directly affect the reliability of testing and certification

Embodiment Construction

[0039] The method of the present invention is to first determine the eUE multi-antenna space angle spectrum representation parameter value and multi-antenna aperture wavelength ratio Value, based on which the eUE multi-antenna correlation matrix β factor is calculated to obtain the corresponding multi-antenna correlation matrix.

[0040] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, not to limit the present invention.

[0041] The method in this embodiment takes the eUE test as an example. For the eUE to be tested, the multi-antenna of the eUE and the physical environment where the eUE is located are treated as a black box, that is, the antenna of the eUE is ignored during the test, and the test signal is multiplied by the corresponding channel. After estimating th...

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 accordingto 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...
