摘要
对码分多址 (CDMA)信号的检测常会遇到使用相同载波频率的系统用户的干扰 (信道内干扰 ) ,或是遇到使用相近频率的用户的干扰 (信道间干扰 )。我们提出采用两阶段检测器。这个检测器并不复杂 ,但能消除大部分的信道内干扰和部分的信道间干扰。
ion: The detection of a code division mutiple access(CDMA) signals is often hampered by the interference generated by system users whose carrier frequencies are the same [i.e, cochannel interference(CCI)] or close to [interchannel interference(ICI)] that used by the desired user. We propose a two-stage multiuser detector. This detector is of modest complexity and is capable of removing most of the CCI and part of the ICI.
