Scintillation and Bit Error Rate Analysis of Lommel Beam

In this paper, we study on-axis (point like) scintillation, change in scintillation index depending on receiver aperture radius, and bit error rate evaluation of Lommel beam. Scintillation index formula is derived using well known Rytov method and numerical values are evaluated benefiting from random phase screen approach. We investigate that scintillation indexes of all types of Lommel beams are less than Gauss beam. In addition, raise in asymmetry parameter c mitigates on-axis and aperture averaged scintillation. We finally conclude that Lommel beam is well ahead in case of bit error rate(BER) under weak turbulent and low signal to noise ratio(SNR) conditions.

Automated summary

This paper investigates the characteristics of Lommel beams, comparing their scintillation index to Gaussian beams and evaluating their performance in terms of bit error rate under weak turbulent and low signal to noise ratio conditions. It is found that Lommel beams exhibit lower scintillation indexes than Gaussian beams and outperform them in terms of bit error rate.
