Ws. Youn et Vk. Bhargava, ORTHOGONAL MULTICARRIER CDMA SYSTEM USING A CONCATENATED ORTHOGONAL PN SPREADING SCHEME/, Electronics Letters, 32(25), 1996, pp. 2318-2320
A new communication scheme combining both MC modulation and DS-CDMA wi
th a concatenated orthogonal/PN spreading scheme is proposed. This sch
eme incorporates the advantages of both DS-CDMA with a concatenated sc
heme, and an MC modulation technique to combat the effect of a multipa
th fading channel, It is shown that the proposed system outperforms th
e MC-CDMA system with a conventional PN sequence.
