论文摘要
在LIFI Attocell网络下行链路上的共通道干扰会大大降低网络性能的速度。多个访问方案的分析对于减轻干扰和提高速率至关重要。在集中监测LED的时分师多访问（TDMA）方案将适合分析的时间划分多重访问（TDMA）方案。这项工作考虑了[1]在M-PAM调制信号上的干扰表征，以得出计划时间安排的attocell网络的goodput g的精确表达式，该表达式在二维中被排列为确定性的正方形晶格。鉴于LED上的TDMA，数值模拟表明，LED可以是最佳时间以最大程度地提高Goodput的时间，这意味着与未测定LED相比，TDMA会减轻attocell网络中的干扰。
Co-channel interference in the downlink of LiFi attocell networks significantly decreases the network performance in terms of rate. Analysis of multiple access schemes is essential to mitigate interference and improve rate. The light emitting diodes (LEDs) being centrally monitored, the time division multiple access (TDMA) scheme over the LEDs will be suitable to analyze. This work considers the interference characterization in [1] over M-PAM modulated signals to derive an exact expression for the goodput G of the time scheduled attocell network, which is arranged as a deterministic square lattice in two dimensions. Given this TDMA over the LEDs, numerical simulations show that the LEDs can be optimally time scheduled to maximize the goodput, which implies that the TDMA mitigates interference in an attocell network compared to the case when the LEDs are unscheduled.
