| 摘 要： | 随着第四代移动通信系统的深入研究,本文介绍了一种新型的无线接入系统方式IDMA.作为一种特殊的CDMA,它采用不同的交织序列来区分用户.它继承了CDMA的很多优点,能支持多用户,具有复杂度低,运算量小的特点.IDMA采用迭代检测技术后,在计算复杂度增加较少的情况下,有效提高了频谱利用率.

| Abstract: | With the intensive research into the 4G mobile communication systems,a new means to wireless access is introduced in this article.As a special form of CDMA,IDMA employs different random interleavers to distinguish users apart.It inherits many advantages from CDMA such as supporting multi-users,low complexity,less number of computations and so on.IDMA adopts iterative detection which can availably elevate the efficiency of frequency in the case of increasing just a little complexity. |
