Application of equivalent structure constant in scintillations and BER found for non-Kolmogorov spectrum
چکیده انگلیسی

The 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.
