• Aperture selection (ApS)
• asymmetrically clipped optical orthogonal frequency-division multiplexing (ACO-OFDM)
• free-space optical (FSO) turbulence channel
• multiple transmit/receive aperture (MTRA)

We propose a novel aperture selection (ApS) scheme for an asymmetrically-clipped-optical-orthogonal-frequency-division-multiplexing-based (ACO-ODFM) multiple-transmit/receive-aperture (MT/RA) system communicating over a free-space optical (FSO) turbulence channel between a pair of cooperating base stations in a vehicular communication system. Our proposed ApS scheme is capable of significantly improving the system's achievable diversity gain, bit error ratio (BER), and throughput, while imposing substantially reduced power consumption and hardware complexity. Our results demonstrate that the proposed system's performance was improved more significantly under strongly turbulent channel conditions.
