本文提出了一种水下自适应阵列接收机结构，利用直接序列码分多址和空间分集合并，以实现可靠的低数据速率多用户通信在异步浅水网络。建议的接收机架构的性能已通过离线处理的海上试验期间获得的数据在1999年夏天在北海进行了验证。结果表明，这种计算效率高的结构是近-远阻力，并提供成功的多用户操作在浅水通道。
This paper proposes an underwater adaptive-array receiver structure that utilizes direct-sequence code division multiple access and spatial diversity combining in order to achieve reliable low-data rate multiuser communication in an asynchronous shallow-water network. The performance of the proposed receiver architecture has been verified by means of offline processing of data acquired during sea trials in the summer of 1999 in the North Sea. Results show that this computationally efficient structure is near-far resistant and provides successful multiuser operation in the shallow-water channel.
