Embodiment Construction

[0040] In the present invention, in order to describe the influencing factors of the RNUT, the RNUT is equivalent to the colored noise source of the RTUT, and the measurement of the spatial receiving sensitivity of the RTUT needs to be performed under the environment of the colored noise source.

[0041] Specifically, set the wireless link corresponding to the RTUT in the MAT to be in a normal wireless transmission and reception working state; when the RNUT is turned on, measure and obtain the RTUT receiving sensitivity of the MAT.

[0042] Preferably, when the RNUT is turned on, the RTUT in the MAT and the wireless links corresponding to the RNUT are both in normal wireless transmission and reception working states.

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Such as figure 1 As shown, the method for measuring the receiving sensitivity of the receiving terminal under test in...

Abstract

The invention discloses a method for measuring receiving sensitivity of a receiving terminal to be measured in a multi-access terminal. The multi-access terminal (MAT) at least comprises a receiving terminal under test (RTUT) and a corresponding antenna, a radio not under test (RNUT) and a corresponding antenna. The method comprises the steps of: setting a radio link corresponding to the RTUT in the MAT to be in a normal wireless sending and receiving working state; and in the state that the RNUT is opened, measuring and obtaining the receiving sensitivity of the RTUT of the MAT. The invention considers the influence of the RNUT on the RTUT to ensure that the receiving sensitivity of the RTUT is measured more accurately, and has the advantages of low requirements on the environment, easy test, simpleness and convenience, and the like.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for measuring the receiving sensitivity of a receiving terminal under test (RTUT, Receiving Terminal Under Test) in a multi-access terminal (MAT, Multi-Access Terminal). Background technique [0002] The rapid development of cellular mobile network, wireless local area network, and radio and television network communication technologies has stimulated people's demand for viewing multi-service content on mobile terminals based on the above-mentioned communication technologies, and multi-access terminals (MAT, Multi-Access Terminal) have emerged, such as , dual-mode dual-standby mobile terminal. [0003] At present, the RTUT receiving sensitivity measurement model of MAT does not consider the influence factor of the non-under-test radio (Radio Not Under Test abbreviated as RNUT) on the RTUT in the actual application scenario. The influence factor is an anisotropic colored...
