随着信息社会的向前发展,人们对新型多媒体业务需求呈现多样化趋势。因此这要求3G网络的的传输速度与质量的要求越来越高。目前我国移动通信使用的TD-SCDMA标准,从技术上来说已经相当成熟与稳定。但受系统自身的影响,如不同制式系统的邻频干扰、时隙干扰等问题的存在,所以还需要我们对一些技术问题进行探索与研究。本文从阐述3G网络信号干扰的类型及原理,以揭示干扰产生的原因;在此基础上就当前技术条件下对干扰的判定方法进行了介绍,最后提出相应的排除对策。
With the development of the information society, there is a diversified demand for new multimedia services. Therefore, this requires that the transmission speed and quality requirements of the 3G network be higher and higher. At present, China’s mobile communications TD-SCDMA standards, technically speaking, has been quite mature and stable. However, due to the influence of the system itself, such as the interference of the adjacent channel of the system in different standards and the interference of time slots, it is still necessary for us to explore and study some technical problems. This paper elaborates the types and principles of signal interference in 3G networks to reveal the causes of interference. Based on this, it introduces the methods to determine interference under the current technical conditions, and finally puts forward the corresponding countermeasures.
