In this letter, a joint algorithm based on look-up table (LUT) and k-means is proposed to compensate the nonlinearity distortion caused by the saturation effect of optical/electrical devices in a photonics-aided microwave communication system at K-band. Adopting the proposed algorithm, we experimentally realize a delivery of 20-Gb/s single-carrier 16-quadrature amplitude modulation signal over 132-m wireless link and the BER satisfies the hard-decision forward error correction threshold of 3.8 x 10(-3). Such a joint algorithm can combine the advantages of LUT and k-means at high optical power. Based on the experimental results, the joint algorithm shows obvious superiority compared with the mere use of LUT or k-means in terms of strong saturation.
