摘要
多载波CDMA(MC-CDMA)是一种把正交频分复用(OFDM)和CDMA结合起来的新一代移动通信系统。本文详细构建了一个MC-CDMA系统的数学模型,并表达出了它的矩阵-向量表示法,在对此系统模型作详细阐述的基础上,创新性地对MC-CDMA进行了线性多用户检测,通过MATLAB仿真结果分析了其解相关检测和最小均方误差检测的优越性。
Multi-carrier CDMA is a new candidate for next generation communication,which combines the Orthogonal Frequency Diversion Multiplexing (OFDM) and CDMA together. The paper specifically constitutes a mathematic modal for MC-CDMA and makes the matrix-vector presentation of it, at the end of this paper the linear MUD is done based on the model. The advantages are showed in the MATLAB simulation figures.
