摘要：
This article presents point-like, aperture averaged scintillation, and bit error rate(BER) performance of cylindrical-sinc Gaussian beam (CSGB). We model atmosphere utilizing random phase screen approach to be up to the complexity of source field expression. Our results indicate that it is possible to generate resistive CSGBs against turbulence considering point-like scintillation. Aperture averaged scintillation results show that all selected beams have lower scintillation index than Gauss beam. Major benefit of CSGBs is seen in BER evaluation in optical wireless communication systems. It is possible to decrease BER10(-7) times lower than Gauss beam at nearly 13 dB signal to noise ratio(SNR).
