论文摘要
我们介绍了指向误差对光学预放大脉冲位置调制（PPM）接收器的平均位误差概率（ABEP）的影响的分析结果。结果表明，梁宽度在ABEP中起着关键作用，并且通过使用亚最佳宽度引入了重大的功率惩罚，尤其是在指向误差时掺有抖动组件时。我们还提供了优化的优化，用于许多指向误差方案的光束宽度，并表明随着额外的信号能量可用，需要增加光束宽度。最佳光束宽度还受PPM调制顺序和光学噪声模式的影响，具有更节能的（更高的调制顺序和较低的噪声）系统，允许更宽的光束。
We present analytical results on the effect of pointing errors on the average bit-error probability (ABEP) of optically pre-amplified pulse-position modulation (PPM) receivers. The results show that the beam width plays a key role in the ABEP and that a significant power penalty is introduced by utilizing sub-optimal widths, especially when pointing errors incorporate a jitter component. We also present the optimisation the beam width for a number of pointing error scenarios and show that increasing beam widths are required as additional signal energy becomes available. The optimal beam width is also affected by the PPM modulation order and the optical noise modes, with more energy efficient (higher modulation order and lower noise) systems allowing for broader beams.
