Design and selection of spread spectrum code sequence is one of the key technologies of CDMA digital honeycomb mobile communication. The design of spread spectrum code sequence is constructing pseudo-random sequence which is possessed of different structure and good performances in order to satisfy the need of CDMA system. At present the m sequence,Gold sequence and Walsh sequence are studied deeply and more used. This paper analyzed the perfromances and characters of spread spectrum sequences in theory and engineering practice,at the same time gave the forming methods of m sequence,Gold sequence and Walsh sequence and so on.
