摘要

多载波码分多址(MC-CDMA)是未来宽带无线多媒体通信系统的最佳候选方案之一。提出了一种新的MC-CDMA系统上行信道估计算法。基于dft的上行信道估计算法通过对每个用户合理的约束和精心设计的前导，在不牺牲系统容量的前提下，可以获得较好的估计精度。计算机仿真验证了该方法的有效性，并给出了结论。

DFT-based uplink channel estimation in MC-CDMA systems

Multi-carrier code division multiple access (MC-CDMA) is one of the best candidates for the future broadband wireless multimedia communication systems. This paper proposes a novel channel estimation algorithm for MC-CDMA systems on the uplink. With reasonable constraint and well-designed preambles for each user, the DFT-based uplink channel estimation algorithm can achieve good estimation accuracy without sacrificing much system capacity. Computer simulation demonstrates the effectiveness of this method and our conclusion is presented.
