海洋水声信道严重的多途特性造成的码间干扰是水声信道高速率数据传输技术所需克服的最大困难，而接收和发射换能器在所用频带的不平坦又加剧了多途的影响.并详细讨论了克服多途效应造成的码间干扰采取的一项重要措施：换能器频谱特性的均衡技术The key problem to be solved in the underwater high speed data transmission technology is the interference between codes caused by the severe multiple path characteristic in the underwater acoustic channel of the sea, and the uneven spectral characteristic of receiving and transmitting transducer in the frequency band used still exacerbate the influence of the multiple path .In the article, one of the most important measures taken in solving the interference between codes caused by multiple path effect is discussed in details, which is the equalization of transducer spectral characteristic.福建省自然科学基
