摘要/Abstract

摘要：

针对现有直接序列扩频码分多址（DS-CDMA）水声通信数据率低且接收复杂度高的问题，提出循环移位扩频多用户通信方法。通过基于M元调制的循环移位扩频技术来有效提高每个用户的数据率，相对DS-CDMA有着更高的带宽效率；利用被动时间反转技术抑制各用户之间的码间干扰和同信道干扰，复杂度低；利用扩频码之间的准正交性提高处理增益。湖上实验研究结果表明在浅水5.27 km距离且复杂多径干扰条件下，利用所提方法可实现10^-2～10^-4的误码率并实现6用户通信，通信速率可达39 bit/s。

关键词: 水声通信, 循环移位扩频, 多用户通信, 被动时间反转

Abstract:

Aiming at the problem of low data rate and high receiver complexity of existing direct sequence spread spectrum code division multiple access (DS-CDMA),a novel code division multiple access (CDMA) using cyclic shift keying (CSK) signaling,namely CSK-CDMA,was proposed for multiuser underwater acoustic communication.The proposed method used the cyclic correlation characteristic of spread spectrum signals with M-ary modulation to provide a higher data rate than conventional.Passive time reversal technology was employed to suppress inter-code interference between users and the co-channel interference.The quasi-orthogonality of spread spectrum code was used to improve the processing gain.Multiuser communications are demonstrated with lake experimental recorded data under the condition of 5.27 km distance and complex multipath interference.The data rate is 39 bit/s/user for 6 users with bit error rate around 10^-2～10^-4.

Key words: underwater acoustic communication, spread spectrum cyclic shift, multiuser communication, passive time reversal
