可见光通信具有环保、安全和能耗低等优点，是第5代移动通信的一个强有力补充。针对多小区多用户多输入多输出可见光通信系统中小区间干扰的问题，文章提出使用基于棱镜阵列的非成像接收机作为接收设备，并讨论了两种多小区划分方案来降低小区间干扰的影响,第1种是动态小区，第2种是非动态小区。仿真结果表明，经过光电探测器选择后，这两种方案都能有效地消除小区间干扰的影响。当用户处于干扰区时，动态小区方案的误比特率（BER）性能更优，但是其计算复杂度较高。当用户都处于非干扰区时，这两种方案的BER性能相同。

Visible Light Communication (VLC) with environmental protection, safety and low energy consumption is a powerful complement to the 5th generation mobile communication. Aiming at the problem of inter-cell interference in multi-cell multi-user Multiple Input Multiple Output VLC (MIMO-VLC) system, a non-imaging receiver based on prism array is uased as the receiving device, and two multi-cell division schemes are proposed to reduce inter-cell interference. The first is a dynamic cell and the second is a non-dynamic cell. The simulation results show that after the Photodetector Selection (PDS), both schemes can effectively eliminate the influence of inter-cell interference. When the user is in the interference zone, the dynamic cell scheme has better Bit Error Rate (BER) performance at the cost of higher computational complexity. The BER performance of the two schemes is similar when the users are in the non-interference zone.
