| 摘 要： | 结合并行转输和多载波调制技术，提出了一种多载波直接序列码分多址模型，对系统在存在窄带干扰的Rayleigh衰落信道下的性能进行了理论分析，并同Rake接收的单载波DS CDMA系统进行了比较。分析和仿真表明：该系统具有较强的抑制窄带及多址干扰的能力，同单载波DS CDMA系统相比，能支持更多的用户数。

| Abstract: | In this paper, a multicarrier DS-CDMA system is proposed by integrating parallel transmission with multi-carrier modulation (MCM) techniques. The model performance over Rayleigh fading channel with narrow-band interference present is analyzed, and compared to the performance of single-carrier Rake DS CDMA system. It is shown from the simulation results that the presented model has the capability of suppressing narrow-band interference and multiple-access interference and can support a larger number of users, compared to the single-carrier DS-CDMA system. |
