We present on-axis, aperture averaged scintillation, and bit error rate performance of Mathieu–Gauss beams (MGB). We model atmosphere utilizing random phase screen. Our investigations show that scintillation indexes of both odd and even modes of MGBs are less than Gauss beam. In the comparison of odd and even modes, odd modes draw the attention with its less scintillation index. In case of aperture averaged scintillation, all types of MGBs are advantageous comparing with Gauss beam but this advantage vanishes with increase in receiver aperture opening. Mitigation in scintillation index brings us 10⁻⁶ times lesser bit error rate (BER) than Gauss beam.

我们介绍了Mathieu-Gauss光束（MGB）的同轴，孔径平均闪烁和误码率性能。我们利用随机相位屏蔽对大气建模。我们的研究表明，MGB的奇数和偶数模式的闪烁指数均小于高斯光束。在比较奇数和偶数模式时，奇数模式以其较低的闪烁指数吸引了人们的注意。在孔径平均闪烁的情况下，与高斯光束相比，所有类型的MGB都是有利的，但是随着接收器孔径开口的增加，这种优势消失了。闪烁指数的减轻使我们的误码率（BER）比高斯光束小10 ^-6倍。
