Abstract

The investigation of high-speed optical orthogonal-frequency division multiplexed-free space optical system using mode division multiplexing of three spiral phased Hermite Gaussian modes has been discussed in this article. The investigation of the system is reported by considering the effect of beam divergence and weather conditions. Square root module technique has been applied at the receiver side and the system performance has been analyzed by using the enhanced detection technique. Results indicate augmentation in the range limit of the system along with improvements in terms of signal quality.
