“…According to equation (18), the interference factor is the ratio of the path loss of the interference channel to the path loss of the effective channel. In addition, an important non-coplanar parameter should be considered.…”

“…In the latest UVC experimental systems, the achievable data rate of LOS UVC within a few meters has reached gigabits per second (Gbps) [11]- [14], while that of NLOS UVC is only up to kilobits per second (Mbps) [15], [16]. Therefore, the most pressing problem facing short-range NLOS UVC is that the data rate is too low to support potential high-quality application scenarios, such as multimedia communication or high-capacity sensor networks [17], [18].…”

To overcome the inherent bandwidth limitation of non-line-of-sight (NLOS) ultraviolet communication (UVC) channel, a novel space division multiplexing (SDM) framework based on non-coplanar rotation angle is established. The influence of SDM structure parameters on inter-channel interference (ICI) is studied to obtain the optimal antenna configuration. And a Gaussian approximate distribution (GAD) signal detection model is presented, which simplifies the calculation of the Bit error rate (BER) of the Photon multiplier tube (PMT) reception and is suitable for complex ICI analysis. Furthermore, a low ICI scheme based on the relationship between BER and the interference factor is proposed to increase the data transmission rate or reduce the alignment configuration. As a result, the maximum data rate increases to 34 Mbps, or the alignment demand decreases by 33.33% at most. Moreover, these analysis results and techniques can be applied to other NLOS scattering optical wireless communication systems.
