摘要 通过对MC—DS—CDMA系统中多址干扰(MAI)的研究,提出了运用最优化波形结合最优化载波间距来减小系统多址干扰的方法。理论分析结果表明,可以用多项式替代法来同时最优化波形和载波间距。仿真结果表明,该方法降低了系统中的多址干扰和误比特率,改善了MC—DS—CDMA系统的性能。 In MC-DS-CDMA systems, the optimization of both carrier spacing and chip waveform can reduce the system multi-access interference. A methodology of the waveform optimization was studied. The results showed that the optimization can reduce the multi-access interference distinctly.
