Chaotic free-space laser communication over a turbulent channel.

چکیده
The dynamics of errors caused by atmospheric turbulence in a self-synchronizing chaos-based communication system that stably transmits information over an approximately 5 km free-space laser link is studied experimentally. Binary information is transmitted using a chaotic sequence of short-term pulses as a carrier. The information signal slightly shifts the chaotic time position of each pulse depending on the information bit. We report the results of an experimental analysis of the atmospheric turbulence in the channel and the impact of turbulence on the bit-error-rate performance of this chaos-based communication system.

متن کاملChannel Capacity of MIMO FSO System under Strong Turbulent Condition
Free Space Optics (FSO) or optical wireless communication is a promising solution for the need to very high data rate point-to-point communication. In FSO communication links, atmospheric turbulence causes fluctuations in both the intensity and the phase of the received light signal, impairing link performance. This intensity fluctuation, also known as scintillation is one of the most important...
