摘要

为了有效地管理VLC-WiFi异构网络的小区间干扰，该文设计基于用户中心接入的动态载波分配(DCAUCA)方法，该方法依据用户请求速率构建大小不同的multi-AP小区，对各multi-AP小区依据用户请求速率与网络服务速率的差值降序排列，并依次为各multi-AP小区的VLC AP分配载波.同时，提出基于VLC AP发射功率控制的小区残余干扰抑制(RISPC)策略以进一步优化干扰管理效果.仿真结果表明，DCAUCA方法相较于对比方法最高可提升52.15%的系统吞吐量与7.10%的用户满意度，RISPC策略相较于DCAUCA方法最高可提升9.66%的系统吞吐量.

Abstract

In order to manage the inter-cell interference of the visble light communication-wireless fidelity (VLC-WiFi) heterogeneous network effectively

a dynamic carrier allocation method based on user centric access (DCAUCA) was designed in this paper

in which multi-AP cells were constructed for users according to user rates and the differences between user request rate and network service rate of each cell was sorted in descending order for the purpose of allocating carriers to each VLC AP sequentially. Furthermore

a strategy called residual interference suppression based on transmitting power control (RISPC) was proposed to further suppress residual interference. Simulation results show that

compared with the comparison method

the DCAUCA improves system throughput by up to 52.15% and user’s satisfaction by up to 7.10%. Compared with DCAUCA

the RISPC improves system throughput by up to 9.66%.
