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 BER ##IMG## [http://ej.iop.org/images/1402-4896/95/11/115501/psabbbd0ieqn1.gif] {${10}^{-7}$} times lower than Gauss beam at nearly 13 dB signal to noise ratio(SNR).

圆柱正弦高斯光束的闪烁和误码率分析

本文介绍了圆柱状正弦高斯光束(CSGB)的点状,孔径平均闪烁和误码率(BER)性能。我们利用随机相位屏蔽方法对大气建模,以适应源场表示的复杂性。我们的结果表明,考虑到点状闪烁,有可能生成抵抗湍流的CSGB。孔径平均闪烁结果表明,所有选定光束的闪烁指数均低于高斯光束。CSGB的主要优势体现在光学无线通信系统的BER评估中。可以降低BER ## IMG ## [http://ej.iop.org/images/1402-4896/95/11/115501/psabbbd0ieqn1.gif] {$ {10} ^ {-7} $}在接近13 dB的信噪比(SNR)时比高斯光束低两倍。
