摘要
干扰消除是移动通信管理的重要组成部分之一。在LTE-A系统中,由于中继技术的引入,给解决小区干扰尤其是小区间干扰提出了更高的要求。通过分析LTE-A系统引入中继后产生的新干扰情况以及依据正交频率复用技术可以有效降低小区间干扰的优势,提出了一种LTE-A中继系统基于OFDMA的干扰解决算法。通过仿真结果表明,该算法有效地降低了小区间的干扰,提高了小区的吞吐量,提升了小区的服务质量。
Interference cancellation is an important component of the mobile communication management.In the LTE-A system,due to the introduction of relay technology,higher requirements has been proposed to solve cell interference,especially inter-cell interference.This paper analyses the new interference from the introduction of a new relay in LTE-A system,according to the orthogonal frequency multiplexing can effectively reduce inter-cell interference.This paper presents a LTE-A relay system,which based on OFDMA interference solution algorithms.The simulation results show that the algorithm is effective to reduce the intercell interference and improve the cell throughput and enhance the community quality of service.
