摘要

数字视频广播-手持卫星服务(DVB-SH)和UMTS网络位于电磁频谱的非常接近的部分，因此可以在相邻的频带中工作。因此，评估它们的共存是最重要的。本文对这两个系统之间的互反干扰进行了研究。提出了一种基于射频覆盖预测的干扰表征方法，并根据与干扰源的距离量化了预期的信噪比和干扰比(SNIR)退化。针对具体用例提供了这些带外辐射影响的示例，并给出了一组现场测量结果。

Mutual interference between DVB-SH and UMTS systems

Digital Video Broadcasting — Satellite services to Handhelds (DVB-SH) and UMTS networks are located in very close portions of the electromagnetic spectrum and can thus operate in adjacent frequency bands. Consequently, an assessment of their coexistence is of primary importance. This paper presents an investigation into the reciprocal interference between the two systems. A method to characterize interference based on RF coverage predictions is proposed and the expected Signal to Noise plus Interference Ratio (SNIR) degradation is quantified on the basis of the distance from the interference source. An example of the impact of these out-of-band emissions is provided for a specific use case and a set of on-field measurements is presented.
