基站间频偏对TD-LTE-A CoMP技术影响的评估

针对协作多点传输技术(CoMP)在实际系统中运用时,基站间频率偏移可能带来的问题,建立合适的系统模型,在不同场景下对基站间频率偏移对于协作多点传输的影响进行了深入的研究。仿真分析表示,基站间频率偏移对协作多点传输技术的性能不会带来太大的影响,引入频偏后系统性能仍较SU/MU-MIMO有较大的增益。这一研究工作为协作多点传输的可行性和有效性提供了有力的支持。

Evaluation of Carrier Frequency Offset on CoMP Technology in TD-LTE-A System

Based on the problems that carrier frequency offset between base stations may brought when CoMP was put into reality,this paper establishes an appropriate simulation model,and does an in-depth research into the performance evaluation of carrier frequency offset on CoMP technology in TD-LTE-A system.The simulation results indicates that carrier frequency offset won＇t bring much decrease of system performance to CoMP technology.Even with carrier frequency offset,CoMP technology still increases system performance greatly over SU/MU-MIMO.The research work of this paper provides theoretical support for the feasibility and effectiveness of CoMP technology in TD-LTE-A system.
