中文摘要：

该文研究了部分相关广义正交序列及N倍时延部分长度D0正交序列,重点对LS（Loosely Synchronized）序列的部分相关特性进行了分析。分析结果表明,LS序列具有4倍时延1/2序列长度部分相关正交特性,经过变换,可构造出基于4倍时延1/2序列长度的部分长度自互补序列和偶时延部分长度互互补序列。在此基础上,该文提出了一种将N倍时延部分长度D0正交序列应用于同步CDMA（Code Division Multiple Access）系统中的方案,可以消除系统的多址干扰。

英文摘要：

In this paper, the generalized orthogonal sequences and N-shift partial length Do orthogonal sequences with partial correlations are investigated. In particular, the partial correlation properties of Loosely Synchronized （LS） sequences are analyzed in details. The results show that LS sequences have partial correlation orthogonal property at 4-shift with half length, which can be utilized to construct partial length auto-complementary sequences and even-shift partial length cross-complementary sequences. Multiple-access interference can be eliminated in synchronous Code Division Multiple Access（CDMA） systems if the N-shift partial length D0 sequences are adopted.
