Abstract
In this letter, we propose a mathematical method to evaluate the bit error rate (BER) of orthogonal frequency division multiplexing with cyclic prefix (CP-OFDM) in an underwater acoustic (UWA) channel with statistical characterization. We adopt general statistical modeling for the UWA channel and specifically study long-distance horizontal UWA transmission in shallow water. Moreover, we perform a rigorous derivation in which the large- and small-scale channel characterization and Doppler shifting are divided into two parts: unified fading and the residual Doppler effect. Furthermore, this approach can be extended to other typical UWA communication channels with different statistical characterizations. Finally, simulation results show good agreement with theoretical results, regardless of whether the motion is drift or intentional movement.
