摘　　要：随着移动通信技术的深入发展,一种新颖的IDMA技术被提出用以区分多用户。交织多址可以看作是一种特殊的CDMA,系统的发送端采用不同交织器来区分用户,接收端则采用低复杂度的码片级迭代检测技术,可以有效提高系统误码性能,另外系统还继承了CDMA的许多优点,拥有良好抗干扰性能和高频谱利用率。With the development of communication technology,Interleave Division Multiple Access(IDMA) have been used to separate users.As a special form of CDMA,IDMA employs different interleavers to distinguish users,and it adopts iterative detection which can improve the BER performance in the case of increasing just a little complexity.IDMA also inherits many advantages from CDMA such as high efficiency and good performance of anti-jamming.

关 键 词：交织多址 交织器 迭代检测
