摘要
MC-CDMA系统是将CDMA和OFDM技术的优点结合在一起的多址方案。首先介绍了OFDM的基本原理,并据此给出MC-CDMA系统的模型,通过对MC-CDMA和DS-CDMA的性能比较,MC-CDMA能提供更高的系统容量,结构更简单,抗干扰性更强,更适用于未来移动通信的需要。
MC-CDMA system is a multiple access scheme that combines the advantages of both CDMA and OFDM technologies. This paper firstly introduces the basic principle of OFDM, then provides the model of the MC-CDMA system. Through the comparison between MC-CDMA and DS-CDMA, we conclude that MC-CDMA is the ideal system to the need of future's communication, since its higher capacity, simpler structure, and better performance in anti-interference.
