摘要
分析多载波码分多址系统的基带发射、接收信号模型以及多径Rayleigh衰落信道模型,进而提出一种系统的通用矩阵分析模型。对多载波码分多址系统的单用户理论误码性能进行了深入探讨,给出了一种新颖的单用户误码率分析方法。数值仿真结果表明:多载波频率分集CDMA系统在无线宽带数据传输中性能大大优于CDMA,具有良好的应用前景。
On the basis of signal analyzing, MC-CDMA system is modeled, and then a universal matrix-analyzing model is advanced. The performance of bit error for single user MC-CDMA in Rayleigh fading channel is discussed,and a novel analyzing method for bit error ratio is proposed. The numerical results of simulation show that the ability of MC-CDMA for wireless broadband data transmission is much better than CDMA, therefore it has a better perspective for business application.
