This paper considers signature waveform design for downlink communications in a multicarrier direct sequence code division multiple access (MC-DS-CDMA) system. The design introduces a carefully chosen phase offset in each carrier to minimize the multiple access interference (MAI). With the proposed signature waveform design, a significant performance improvement over the existing MC-DS-CDMA systems is achieved.
