  • Abstract
    A novel Orthogonal Expanded Walsh Code (OEWC) suited in DS-CDMA spreading is presented in this paper. Although some processing gain increased, the OEWC can increase channel anti-interference and transmission security since of its elongated horizontal length. Moreover, it can be applied with MPSK to modulate one of M signal units expressed with a chip of OEWC. This plus the higher security and anti-interference abilities make OEWC of interest to designers of next-generation CDMA systems.
