Interference Analysis of Coexistence of TD-LTE and WCDMA System
Dawei Xu · Microprocessors · 2012
WCDMA,one of the 3G standards,is commercially operated in China successfully.TD-LTE,as the evolution of TD-SCDMA,will be operated in the future.Therefore,the two systems may coexist in some area.Accordingly,the inter-system interference caused by coexistence would degrade the performance of both.In this paper,minimum coupling loss(MCL) method is adopted to analyze the coexistence interference.We also calculate the isolation requirements,and investigate the antenna installation method,which can reduce the intersystem interference effectively.
