The high data rate communication systems require modulation techniques that improve the band efficiency and system robustness against fading. One of the modulation methods that can be used to accomplish these demands is MC-CDMA. In this paper, the authors consider the uplink scenario of a single cell Multi-Carrier Code Division Multiple Access (MCCDMA) in which the channel between a given user and the base station receiver is assumed known and stable for the duration of the transmission. They propose an algorithm that uses the greedy interference avoidance method as well as power update to adapt the transmitter waveform of users.
