非周期自相关函数除左、右移位端外均为零旁瓣的有限长序列可称为移位正交有限长序列，可有效降低直接序列扩频通信系统中的码间干扰。本文提出了一组族长为2/sup /spl nu//或2/sup /spl nu/+1/，长度为2/sup/spl nu//+1，/spl nu/=1，2，3，…的实值移位正交有限长序列的综合.适用于快速相关处理。序列通过卷积来自长度为2和5的序列的/spl nu/+1原始或顺序反转的基本序列来合成。序列的快速相关被分解为（/spl nu/+1）级相关。
The finite-length sequence whose non-periodic autocorrelation function takes zero sidelobes except at left and right shift ends can be called the shift-orthogonal finite-length sequence, and is effective to reduce the intersymbol interference in a direct-sequence spread-spectrum communication system. This paper proposes the synthesis of a set of real-valued shift-orthogonal finite-length sequences which has family size 2/sup /spl nu// or 2/sup /spl nu/+1/ and length 2/sup /spl nu//+1, /spl nu/=1, 2, 3, ... and is suitable for the fast correlation processing. A sequence is synthesized by convolving the /spl nu/+1 original or order-reversed elementary sequences from the sequences of lengths 2 and 5. The fast correlation for the sequence is decomposed to the (/spl nu/+1)-stage correlations.
