In previous studies, the receivers in indoor visible light communication (VLC) were usually fixed. However, in reality, the receivers in VLC have random locations and orientations. Therefore, it is important to consider these random factors for performance analysis in VLC. In this paper, we consider a typical VLC system with a fixed transmitter and a random receiver. Two types of receivers are investigated: (1) those with random location and (2) those with random orientation. Based on the established system model, the statistical characteristics of the channel were obtained, and closed-form expressions of the average channel capacity and the outage probability were derived, respectively. Finally, numerical results verified the accuracy of derived theoretical expressions. Moreover, the effects of the nominal optical intensity, the dimming target, the transmitter height, the receiver zone’s radius, the outage threshold, and the Lambertian emission order on system performance were also provided.

对与随机接收器进行可见光通信的现实性能分析

在以前的研究中，室内可见光通信（VLC）中的接收器通常是固定的。但是，实际上，VLC中的接收器具有随机的位置和方向。因此，重要的是要考虑这些随机因素，以便在VLC中进行性能分析。在本文中，我们考虑具有固定发送器和随机接收器的典型VLC系统。研究了两种类型的接收器：（1）位置随机的接收器和（2）方向随机的接收器。在建立的系统模型的基础上，获得信道的统计特性，并分别得出平均信道容量和中断概率的闭式表达式。最后，数值结果验证了推导理论表达式的准确性。此外，标称光强度，调光目标，
