摘要/Abstract

摘要： 对于一类正整数J, 利用两值自相关序列和四相最优序列, 构造了一类新的具有参数(2^2J-1,2^J+1,2^J+1)$的四相序列集. 新构造的序列集达到了Welch下界, 适用于CDMA通信系统.

关键词: CDMA通信, 理想两值自相关序列, 四相最优序列, Welch界

Abstract: Based on sequences with two-level correlation and optimum quadriphase sequences, a new family of quadriphase sequences with parameter (2^2J-1,2^J+1,2^J+1) is proposed for a class of positive integers J. The new sequences family is optimal with respect to Welch’s lower bound on the maximum nontrival correlation value and it is suitable for CDMA.

Key words: CDMA comunication, Sequences with ideal two-level autocorrelation, Optimum quadriphase sequence, Welch’s bound
