Abstract

Radio on Free-space optical communication systems have been gaining much attention due to their high bandwidth capabilities, addressing the emerging high demands for massive data transfers in wireless communication networks without the need for optical fibers. Thus in this work, we present a single-input multiple-output orthogonal frequency division multiplexing wireless optical communication system with phase shift keying and maximum ratio combining on the receivers' side. Analytical closed-form expressions are extracted for the estimation of the system's average BER, taking into account the atmospheric turbulence and pointing errors effects. The latter is modeled by the gamma-gamma distribution. Finally, numerical results are presented for various realistic turbulence conditions, spatial jitter influence and diversity options.
