摘要
为了满足未来终端多样化的需求,异构网络技术应运而生,但是随之带来的蜂窝小区内以及小区间干扰问题已经成为制约未来无线网络发展的关键因素之一。该文针对此问题,在合作博弈理论的基础上,提出了一种与距离因子有关的干扰协调算法。经过建模仿真,所提算法在保证用户正常通信的前提下,减小了异构网络的干扰,提高了系统性能。
In order to meet the demand of future terminal diversification, heterogeneous network technology emerges as the times require, at the same time the intra-cell interference and inter-cell interference have become one of the key factors that restrict the future development of wireless networks. In response to this problem, this paper proposes an interference coordination algorithm based on the cooperative game theory related to a distance factor. After modeling and simulation, the proposed algorithm can reduce the interference of heterogeneous network and improve the system performance under the premise of guaranteeing normal communication.
