摘要
并行多载波传输理论与CDMA技术的结合,是目前研究的热点之一。文章介绍一种新的无线通信技术———基于OFDM的多载波CDMA技术,给出系统模型和特点,并与CDMA技术加以比较,证明前者在频谱频率、抗多径干扰能力、信道估计、功率控制等方面更胜一筹的优势及未来良好的应用前景。
In this paper we introduce a new wireless telecommunication technology: DFDM based multi-carrier CDMA system. We present its structure and characteristics, and compare it with CDMA system. In the end we draw a conclusion that MC-CDMA is much better than CDMA, and MC-CDMA has the advantages in spectral frequency, anti-interference ability, channel estimating and power controlling. This technology will have good application prospect in the future.
