Problems solved by technology

[0004] At present, the receiving sensitivity measurement model of the receiving system under test (RTUT, Receiving Terminal Under Test) of the multi-mode mobile terminal MAT does not consider the radio under test (RNUT, Radio Not Under Test) receiving system RTUT under test in actual application scenarios. The influencing factor of the receiving system RTUT under test is an anisotropic colored interference
The objective existence of RNUT causes the spatial reception sensitivity of RTUT to be significantly different from that of RTUT alone

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039]The method and system for measuring the spatial receiving sensitivity of the receiving system under test of the MAT terminal of the present invention are aimed at multi-mode coexisting terminals and the situation of multi-mode normal working conditions at the same time, and the radio not under test (RNUT, Radio Not Under Test) The influencing factors of the receiving system RTUT under test are regarded as interference, and the interference from the RNUT is added to the RTUT wireless signal through a wired link, and the mutual power ratio is adjusted to realize the space of the receiving system RTUT under test. A measure of receiver sensitivity. Generally speaking, it is an improved measurement method and system based on the equivalent noise method.

Abstract

The invention discloses a system and a method for measuring space receiving sensitivity of a multimode terminal. The system comprises a receiving terminal under test (RTUT), an antenna corresponding to the RTUT, a simulator of the RTUT, an antenna corresponding to the simulator, a radio not under test (RNUT) and a simulator corresponding to the RNUT. The method comprises the following steps of: making a plurality of communication links, including the RTUT and the RNUT of the multi-access terminal (MAT) in a normal sending and receiving working state; coupling a transmitting signal of the RNUT to a receiving signal of the RTUT; regulating relative power between the RTUT and the RNUT and the simulator of the RTUT; and measuring to obtain the space receiving sensitivity of the RTUT of the MAT. The measurement system and the measurement method are easy to implement and have the advantages that: the requirement on environment is low, the measurement system and the measurement method are easy to test and the like.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a system and method for measuring the spatial receiving sensitivity of a multi-mode terminal. Background technique [0002] The rapid development of communication technologies such as cellular mobile networks, wireless local area networks, and radio and television networks has stimulated people's demand for viewing multi-service content on mobile terminals based on the above-mentioned communication technologies, so the multi-mode mobile terminal MAT (Multi-Access Terminal) appeared . This kind of MAT terminal uses a variety of communication technologies to provide users with a variety of business services, such as WLAN / GSM multimedia mobile phones, GSM / WCDMA dual-mode mobile phones, GSM / Bluetooth mobile phones, etc. Since this type of terminal integrates multiple functions, it greatly This enriches the user's business choices and improves the user experience.
