Abstract :
In this paper, the problem of optimal PN sequence design for quasi-synchronous (QS) DS-CDMA communication systems is formulated, and classes of optimal PN sequences which have good pseudorandomness and small cross-correlation values for some range of offsets are designed. The new results are compared with the commonly used PN sequences, and the system performances of the QS CDMA systems using different PN sequences are also evaluated
