Abstract
Disclosed is a channel-dependent multi-carrier code division multiple access (MC-CDMA) technique with adaptive spreading codes. Adaptive spreading codes are used for each subcarrier per user which increase the security level of conventional MC-CDMA. Two different map designs are proposed: fixed and adaptive interval maps. These maps are shared among all nodes and gives information about the spreading code sequences for corresponding channel gains.
