2.1G频段cdma2000与LTE系统干扰共存的一种确定性分析
Method of Interference Coexistence Analyzing between CDMA2000 and LTE System at 2.1GHz band
近年来CDMA数据业务发展迅猛，现有800M频段的热点地区覆盖日趋饱和，产生了在2.1G频段做数据业务分流的需求。而由HRPD向着频谱利用率更高的LTE系统演进，是数据业务未来发展方向。本文研究了HRPD向LTE演进中的干扰共存课题，提出了基于网络拓扑结构的确定性分析方法，针对两系统共存下的四种典型场景，得出系统间共存所需的隔离度，并给出了相应的干扰规避措施。
In recent years, CDMA data services have been rapidly developing, and 800MHz band for hot spots coverage saturated increasingly, resulting in a growth demands of data distribution on 2.1GHz band. And an evolution from HRPD to LTE will be a future direction for a better splectrum efficiency. In this paper, the interference coexistence during the evolution from HRPD to LTE was studied and a method of interference coexistence analyzing based on network topology was proposed. Under four typical scenarios, the proper isolation between two systems was culculated and corresponding avoidance measures was proposed.
