摘要

In the paper, a novel method, which exploits both the Orthogonal Frequency Division Multiplexing (OFDM)-Code Division Multiple Access (CDMA) technique and the time reversal mirror technique, is investigated to realize multi-user underwater acoustic communication. By taking advantages of these two techniques, the proposed method has the capability of effectively suppressing multi-path interference, reducing the error rate, enhancing the processing gain and improving user capacity. Simulations verify the correctness and effectiveness of the proposed method.
