摘要：

In this paper, the performance of multi-hop free-space-optical (FSO) communications systems over atmospheric turbulence fading channel along with pointing error effects is analyzed considering Pulse Position Modulation (PPM). The analysis is done under weak atmospheric turbulence i.e. Lognormally distributed and transmission using multi-hop which is established on amplify-and-forward relays. We illustrate combined probability density function for multi-hop FSO system. The numerically found results show that the multihop transmission along with M-ary PPM is a good solution for obtaining desired Bit Error Rate (BER) under the effects of weak turbulence and pointing error.
