光无线通信是实现高速下一代蜂窝网络的一种有效的潜在解决方案。由于激光光源，特别是垂直腔面发射(VCSEL)激光器与发光二极管(LED)光源相比具有更高的调制速度，本文将其用于数据传输。为了管理多用户干扰，实现了速率分裂(RS)，其中用户的消息被分成公共部分和私有部分。然而，RS在高密度网络中的性能受到限制。因此，考虑了特别适合于高密度网络的分层速率分裂(HRS)。实验结果表明，VCSEL具有较高的数据传输速率。此外，与RS相比，HRS更适合在光网络中实现高性能。
Optical wireless communication is an effective potential solution for enabling high speed next generation cellular networks. In this paper, laser sources, in particular, vertical-cavity surface-emitting (VCSEL) lasers are used for data transmission due to their high modulation speed compared with light emitting diode (LED) sources. To manage multi-user interference, rate splitting (RS) is implemented where the message of a user is split into common and private parts. However, the performance of RS is limited in high density networks. Therefore, hierarchical rate splitting (HRS) particularly suited in high density networks is considered. The results demonstrate the high data rate achieved by using VCSELs. Moreover, HRS is more suitable for achieving high performance in optical networks compared with RS.
