为提高223~235 MHz频段频谱的使用效率,满足行业用户宽带应用需求,在该频段引入了离散窄带载波聚合宽带系统。为解决系统间电磁兼容问题,对宽带系统和带内窄带无线数据传输系统进行了单站干扰分析和集总干扰分析,还对宽带系统和带外广播电视系统进行了确定性计算干扰分析。最后,基于干扰计算结果提出了频率使用的可行性建议。
Discrete carrier aggregation broadband systems were introduced in the 223~235 MHz band to improve spectrum utilization efficiency and to meet the broadband application demand of industrial users. The interference between broadband system and in-band narrow band wireless radio were analyzed considering both single station interference and aggregated effect. Also
the interference between broadband system and out-of-band TV broadcasting system were calculated. Finally
the feasibility of frequency usage was proposed based on the interference calculation results.
