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.
