| 摘 要： | 多载波码分多址技术是第三代数字通信系统研究中重要课题之一，其主要特点是采用多载波并行传输，成为通信系统提高传输速率的一种有效方法。水声通信在远距离传输时通信速率通常比较低，本文将水声扩频通信与无线电通信中这一成熟技术加以结合，以提高水声通信的传输速率，给出了UW—MC—CDMA系统并进行了分析。

| Abstract: | Multi-cartier CDMA is an important subject in the third generation mobile communication. The main characteristic of CDMA is parallel transmission, which effectively enhances transmission speed. Taking into account the slow nature of long-range underwater acoustic transmission, this paper combines underwater acoustic spread spectrum communication with the multi-carrier technique widely used in wireless communications in order to improve transmission efficiency. An UW-MC-CDMA system is described, and its advantages and disadvantages discussed. |
