首发时间:2010-12-23
摘要:文章首先介绍了LTE-Advanced系统中所采用的载波聚合技术,随后采用静态蒙特卡洛仿真方法,从系统间的地理位置偏移,功控参数以及ACIR(Adjacent Channel Interference Ratios)三个方面着手,研究LTE-Advanced系统中的多载波聚合技术对现有TD-SCDMA系统的干扰。根据仿真结果,分析了载波聚合场景下,系统偏移和功率控制参数对TD-SCDMA系统的影响,并对未来研究LTE-Advanced和TD-SCDMA系统干扰共存问题给出了相应的合理建议。

Interference Research on LTE-Advanced System with Carrier Aggregation to TD-SCDMA System
Abstract:This paper introduces the carrier aggregation technology of LTE-Advanced system firstly. Then, based on the static Monte Carlo simulation method, interference research on LTE-Advanced system with carrier aggregation to TD-SCDMA system from the aspects of relative positions, power control and adjacent channel interference ratios(ACIR) is done. According to the simulation results, the effect from system offset and/or power control parameters are analyzed, and the corresponding reasonable suggestions for the future study on interference coexistence between LTE-Advanced system and TD-SCDMA system are given.
