Aiming at the combined effects of the Exponentiated Weibull atmosphere turbulence, aero-optical effects and pointing errors on space optical links, the bit error rate (BER) performance of the orthogonal frequency division multiplexing (OFDM) optical communication link is investigated. OFDM links adopted PSK modulation. The closed-form expression for average bit error rate is derived based on a Meijer's G function. The relationship between the BER performance and the transmitted optical power under different parameters such as the atmosphere turbulence, the normalized jitter standard deviation and the normalized beam-width is analyzed by simulation. The results show that the BER performance is similarly improved in different intensity turbulence by increasing the transmitted optical power. The BER performance is obviously improved by increasing the transmitted optical power when the normalized jitter standard deviation is less than 0.7 and the modulation order is less than 4.
