Interference Analysis of TD-LTE and TD-SCDMA System Coexistence
Pei Zen Chang, Yongyu Chang, Jing Zhou, Dacheng Yang · 2010
TD-SCDMA, as one of the 3G mobile system, is commercially operated in China successfully. TD-LTE, as the evolution of TD-SCDMA, will be operated in the future. However, these two systems may coexist in one area. The inter-system interference may degrade the performance of both. In this paper, we analyze the coexistence interference by minimum coupling loss (MCL) method. The isolation requirements are calculated, and the antenna installation method, which can reduce the inter-system interference effectively, is also investigated.
