Coding performance of non-interleaved non-memoryless optical wireless channels

摘要

Over the last two decades there has been increasing interest in a free-space optical communication (FSO) as a backup or alternative to radio frequency communication. The main disadvantage of FSO through the atmosphere is related to time-varying turbulence-induced changes in the channel. Theoretical coding error performance analysis of such channels is challenging due to the complicated multidimensional integration that is required. In this paper, the coding error performance is analyzed using simulations with a recent non-memoryless optical channel simulator. The simulation results confirm theoretical analysis and show almost negligible influence of the channel memory on coding performance.
