摘要
码分多址（ＣＤＭＡ）技术已作为第三代数字移动通信及个人通信系统的无线接入技术进行广泛的研究和应用．而ＣＤＭＡ系统中扩频序列问题一直是ＣＤＭＡ技术中的关键问题．文献［４］给出了ＳＣＤＭＡ系统中的扩频序列实数加编码的新方法，但对构造具有纠错能力的扩频序列至今尚未发现．本文给出了ＳＣＤＭＡ系统中具有纠错能力的一类新的扩频序列和它的译码算法．
CDMA system has been widely studied and used as the third generation wireless access technology for mobile and personal portable communication,and the spread spectrum sequences in CDMA system has been the key question of CDMA technology.A new approach to the design of codes for S CDMA system was given by G.H.Khachatrian and S.S.Markirossian,but the method for constructing the spread spectrm sequences with error correcting capacity has not been discovered up to now.In this paper,a new family of spread spectrum sequences with error correcting capacity for S CDMA and its decoding algorithm are given.
