中文摘要： 因具有码分多址、频带共享、抗干扰和抗截获等一系列优点，跳频扩频通信技术在军事无线电通信、民用移动通信、现代雷达和声纳等电子系统中具有重要的应用。在跳频通信系统中，用于控制载波频率的伪随机地址码称为跳频序列。跳频序列的(Hamming)相关特性对序列的捕获系能和捕获时间有着直接的影响，也是衡量通信系统多址干扰性能的重要指标。相对于周期相关特性，跳频序列的部分相关特性是更为一般和更为实用的序列特性，然而其研究却相对甚少。本课题将围绕具有最佳部分相关特性的跳频序列设计展开研究：（1）跳频序列部分相关理论界的研究，着重研究基于编码理论界的部分相关理论界；（2）最佳部分相关的跳频序列设计研究，主要基于部分指数和理论、d-form理论和array-structure理论进行设计。本项目的研究成果将为评价跳频序列部分相关性的优劣提供重要的参考标准，同时为通信系统提供更多具有最佳部分相关特性的跳频序列。

英文摘要： Frequency-hopping spread spectrum is one of spread coding technologies in communication systems which has a series of advantages such as code-division multiple access, band sharing, anti-interference, and anti-jamming. This technology plays a very important role in many practical applications such as military wireless communications, civil mobile communications, modern radar and sonar electronic systems, etc. The pseudorandom codes used to specify which frequency will be used for transmission at any given time are referred to as frequency-hopping sequences (FHSs). The (Hamming) correlation properties of FHSs directly influence the captured performance and time of the involved sequences, which are also an important measure for the multiple access interference performance of the communication systems. Compared with the traditional periodic correlation, the partial correlation of FHSs is more general and more useful for pratical applications, but receives less attention. In this project, we mainly concentrate on the theory related to FHSs with good partial correlation properties. Specifically, we will study (1) bounds on the partial correlaiton of FHSs with an emphasis on the ones based on the bounds from coding theory; (2) design of FHSs with optimal partial correlaiton properties for which the theory of partial e
