Research on the Relativity of Spread Spectrum Sequence

Design and selection of spread spectrum code sequence is one of the key technologies of CDMA spread spectrum 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 are studied deeply and more used.Some scholars have put forward certain really orthogonal code.This paper analyzed the performances and characters of spread spectrum sequences,at the same time gave the forming methods of various sequence codes.
