摘要

研究了水声直接序列扩频通信中拟正交序列的性能。研究了一种以拟正交序列为短码的码分多址通信系统。讨论了拟正交序列抗码间干扰和多址干扰的能力，并计算了系统的容量。计算机仿真结果表明，拟正交序列在水声信道中具有较好的鲁棒性。

Application of quasi-orthogonal sequence in underwater acoustic DSSS communication system

This article deals with the performance of quasi-orthogonal sequence in underwater acoustic direct sequence spread spectrum communication. A code division multiple access communication system adopting quasi-orthogonal sequences as short code is considered. The capability of a quasi-orthogonal sequence in combating intersymbol interference and multiple access interference is discussed and the capacity of the system is calculated. Computer simulation showed that the quasi-orthogonal sequence is more robust in an underwater acoustic channel.
