摘要
小区间干扰严重影响了多小区系统的性能,为了降低小区间干扰的影响,研究了多小区多用户多输入多输出可见光通信(MIMO-VLC)系统的性能,使用基于孔的角度分集接收机作为接收设备,通过选择合适的LED配置,对干扰区进行了优化,并讨论了2种多小区实现方案:第一种是动态小区划分;第二种是光电探测器选择(PDS)消除小区间干扰。仿真结果表明:当小区中有用户处于干扰区时,对于这个小区中的用户,动态小区划分方法的误码率(BER)性能更优,但这个小区中用户的位置会对其它小区中用户的性能产生影响,并且其计算复杂度较高;对于PDS消除小区间干扰方法,一个小区中用户的BER性能不受其它小区用户位置的影响,其计算复杂度较低;当用户都处于非干扰区时,这2种方法的BER性能相同。
Abstract
The performance of multi-cell systems has been seriously affected by inter-cell interference. In order to reduce the influence of inter-cell interference, the performance of multi-cell and multi-user multiple input multiple output visible light communication (MIMO-VLC) system is studied. The angle diversity receiver based on the hole is used as the receiving device, and the interference area is optimized by selecting the appropriate LED configuration, and two multi-cell implementation schemes are discussed. The first is dynamic cell division, and the second is photodetector selection(PDS) to eliminate inter-cell interference. The simulation results show that: when there are users in the interference zone in the cell, the dynamic cell division method has better bit error rate(BER) performance for the users in the cell, but the location of users in this cell will affect the performance of users in other cells, and its computational complexity is high. For PDS method to eliminate inter-cell interference, the BER performance of users in a cell is not affected by the location of users in other cells, and its computational complexity is low. When users are all in the non-interference zone, the BER performance of the two methods is the same.
