Exact analytical BER expression in FSO using α-μ distribution proposed as an approximation of gamma-gamma PDF

摘要

In this paper we present a novel analytical expression for the bit error rate under ON-OFF Keying (OOK) modulation for Free Space Optical Communication using α-μ distribution. We perform numerical comparison between the PDF, CDF and BER using α-μ and Gamma-Gamma distribution. The relative error between PDF and CDF of Gamma Gamma and α-μ demonstrates the viability of α-μ as a alternative to Gamma-Gamma distribution.
