摘　　要：讨论了在典型室内无线信道环境中 ,多址干扰对直扩多载波 CDMA并行捕获系统性能的影响 .比较了多址干扰影响下的直扩多载波 CDMA和直扩单载波 CDMA的捕获性能 .通过仿真和分析计算得到的平均捕获时间评价直扩多载波Multi address interference's effect on parallel acquistion performance of DS Multi carrier CDMA system under typical indoor radio channel is discussed.Moreover,a comparison of acquistition performance impairment produced by the MAI of DS MC CDMA and DS single carrier CDMA is also made.Results are given in terms of average acquistion time obtained by means of simulations and analytical computation.

关 键 词：多载波CDMA 多址干扰 捕获性能
