摘要
本文首先介绍了MC-CDMA和OFDMA两种多址方式;然后提出了利用OFDMA来扩展MC-CDMA系统多址容量的新方法。通过理论分析我们可以知道,新的方法可以有效提高MC-CDMA系统的多址容量。我们对新方法进行了计算机模拟,证明了新方法的可行性和有效性。
In this paper, firstly we introduce the two multiple access method: MC-CDMA and OFDMA, then we give a new approach to increase the multiple access capacity of MC-CDMA system using OFDMA. Through analysis, we can know that this new approach can efficiently increase the capacity of the MC-CDMA system. By computer simulation, we demonstrate the feasibility and validity of the new approach.
