序列偶作为一种最佳离散信号在扩频通信、雷达、声纳、导航、电子对抗、遥测遥控、信息加密等众多领域有广泛的应用前景。构造序列偶的研究也能促使组合设计新概念和新理论的产生。本文对序列偶的性质、构造方法、应用的数学工具以及现阶段取得的研究成果进行了综述,并指出了序列偶研究领域未来的发展方向。
sequence pairs as a perfect discrete signal has a wide range of applications in many fields such as spread spectrum com-munication, radar, sonar, navigation, telemetry and remote control, information encryption and so on. In addition, the research on the constructions of the sequence pairs may promote the generation of both the new concept and theory of combinatorial design. In this paper, the characters, the construction methods, the mathematical tools used and the research results of the sequence pairs are surveyed and the study of the future directions are pointed out.
