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.

超宽带无线通信中的新型二维互补序列

在超宽带(UWB)无线通信中，多载波CDMA被认为是CDMA和OFDM的结合。然而，即使到目前为止，适用于由一组正交子载波组成的OFDM信号的高效CDMA方案仍在研究和探索中。本文提出了一种新的“二维互补序列”(two - dimensional complementary sequence, TDC)及其在MC-CDMA系统中的应用。同时，提出了一种构造该序列的算法。实践证明，该方案具有低PAR值(3db以内)、高带宽效率和高传输能力的优点。
