| Abstract: | Two typical kinds of one-dimensional spread spectrum technology, i.e. DS-CDMA and MC-CDMA, are simply presented in this paper. Based on the previous analysis, this paper focuses on the introduction of a novel spread spectrum technology, i.e. two-dimensional spread spectrum technology. And also it provides a detailed discussion of the transmitter and receiver of a multicarrier two-dimensional CDMA system that integrates this technology. |
