光无线（OW）系统通常会受到多径传播和背景噪声形式的定向干扰的影响。我们提出了一个完全扩散的OW系统，采用了一种新的三角金字塔复眼分集接收器（PFDR）的原始结果。在通信层上的各个位置处评估接收到的脉冲形状，并且确定在金字塔的三个面上收集的背景噪声。结果表明，通过优化PFDR的视场，可以减少定向背景干扰，改善接收脉冲波形。计算的错误概率显示出显着的改善时，我们优化的PFDR天线，而不是传统的光探测器在传统的漫射光无线系统中使用。
Optical wireless (OW) systems are generally impaired by multipath propagation and directional interference in the form of background noise. We present original results for a fully diffuse OW system that employs a novel triangular pyramidal fly-eye diversity receiver (PFDR). The received pulse shapes are evaluated at various locations on the communication floor and the background noise collected on the three faces of the pyramid is determined. It is demonstrated that, through optimization of the PFDR field-of-view, the directional background interference can be reduced and that the received pulse shape can be improved. The computed error probability shows a marked improvement when our optimized PFDR antenna is used instead of the conventional photodetector used in traditional diffuse optical wireless systems.
