Scintillation and bit error rate calculation of Mathieu-Gauss beam in turbulence

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.
