Abstract :
Subcarrier intensity modulation is analyzed for general order rectangular quadrature amplitude modulation over the Gamma-Gamma turbulence channels. Closed-form expressions of average symbol error rate are derived using a series expansion of the modified Bessel function and a moment generating function approach. Truncation error analysis and asymptotic error rate analysis are also presented. Numerical results demonstrate that our closed-form expressions are highly accurate.
