Abstract
In ultra wide band (UWB) wireless communications, multicarrier CDMA has been considered as a combination of CDMA and OFDM. However, even until now, the efficient CDMA scheme suitable for OFDM signal composed of a set of orthogonal subcarriers is still under study and searching. In this paper, we present a novel "two dimensional complementary sequence" (TDC) and its application in MC-CDMA system. Meanwhile, an algorithm to construct this sequence has been built up. It has been proved that the new scheme can offer a low PAR value (within 3 dB) as well as high bandwidth efficiency and high transmission.
