(2014). Application of equivalent structure constant in scintillations and BER found for non-Kolmogorov spectrum. Optic Communications, 310, 109-113. http://dx.doi.org/10.1016/j.optcom.2013.07.0690030-40181873-0310https://doi.org/10.1016/j.optcom.2013.07.069https://hdl.handle.net/20.500.12416/13475The evaluation of system parameters in the non-Kolmogorov turbulent atmosphere involves the structure constant valid at the relevant non-Kolmogorov power law exponent. In some of the existing results, the comparisons of system parameters found under the Kolmogorov and non-Kolmogorov turbulences were made by using the same structure constant for all the power law exponents of the non-Kolmogorov spectrum. In this paper, we evaluate the scintillations and the average Bit Error Rate (< BER >) for the flat-topped and the annular beams in non-Kolmogorov turbulence, this time using the equivalent structure constant which is now different for all the power law exponents. It is observed that the scintillations and the < BER > show completely different behaviour when evaluated with the equivalent structure constant as compared to evaluations with constant structure constant.
