多模多待终端电磁干扰测试方法
Inter-mode Interference Measurement Method for Multi-mode Multi
-standby Mobile Terminals
摘要 针对多模多待终端,提出一种空间电磁干扰测试方法,对其各模组间的电磁干扰程度进行测控。在多模组并发工作状态下,通过扫频测试寻找被测模组受扰最严重信道,然后测量被测模组在该信道上的接收灵敏度;通过对比被测模组在单发和与其它模组并发状态下的灵敏度,观测电磁干扰程度。实测结果表明,上述方法可以有效检测多模终端并发状态下的灵敏度以及各模组间的电磁干扰程度。

Abstract In order to observe the effect of inter-mode interference (IMI),we propose an
over-the-air IMI measurement method for the multi-mode multi-standby terminals.First
the frequency swept test is applied to the module under test (MUT) to find the channel
suffering the strongest IMI from other modules.Then the receiver sensitivity of MUT is
measured on the channel with strongest IMI, with other modules working concurrently
By comparing the receiver sensitivity of the MUT with and without other modules
working concurrently,it is able to observe the influence of IMI on the MUT.Measurement
results show that the proposed test method can effectively show the receiver
sensitivity of the terminals when multiple modules operates concurrently, as well as
the extent of the IMI.
Keywords multi-mode multi-standby terminal; inter-mode interference; over-the-air
