摘要：
Turbulence can distort the signal wavefront in free space optical (FSO) communications, leading to errors. The state-of-the-art method for correcting distortions is adaptive optics (AO). We show that improvements in turbulent FSO communication link performance can be obtained using a few-mode optical pre-amplified receiver, without AO. We compare pre-amplified few-mode and single-mode receivers for both OOK and DPSK modulation formats.
