Abstract

It is well-known that free space optical communications through a turbulent atmosphere are adversely affected by scintillation noise. This paper reports on the experimental demonstration of a two-colour common mode rejection technique to mitigate atmospheric scintillation noise. Real-time equalisation was achieved for both analogue (amplitude modulated PAL composite video) and digital (quadrature amplitude modulated) signals.
