The dynamics of errors caused by atmospheric turbulence in aself-synchronizing chaos based communication system that stably transmitsinformation over a $\sim$5 km free-space laser link is studied experimentally.Binary information is transmitted using a chaotic sequence of short-term pulsesas carrier. The information signal slightly shifts the chaotic time position ofeach pulse depending on the information bit. We report the results of anexperimental analysis of the atmospheric turbulence in the channel and theimpact of turbulence on the Bit-Error-Rate (BER) performance of this chaosbased communication system.
