IDMA系统中交织器研究现状

近年来,香港城市大学李坪教授提出的交织分多址(IDMA,Interleaver Division Multiple Access)作为一种新的多址技术已经在各个方面均得到了广泛的研究。交织多址是根据不同的交织器来区分用户的,因此,交织器的设计是IDMA系统中的一个关键技术。许多学者在传统交织器的基础上,提出了多种适用于IDMA系统的交织器设计方案。对国内外关于IDMA系统中交织器的设计方案分类进行阐述与归纳总结,并比较了各种交织器设计方法的优缺点。

Overview on the Research of the Interleavers Used in IDMA

In recent years,As a new multiple access technique,Nowadays IDMA（Interleaver Division Multiple Access（IDMA） has been extensively all aspects of the study,which,as a new multi-access technology was proposed by Professor Li Ping in the City University of Hong Kong.In,receives much study and research IDMA distinguishes the user,in accordance with different interleavers are used to distinguish the user,thus,designing,and thus the design of interleavers is becomes a key technologywork in IDMA system.Based on the traditional interleavers,a lot of adaptivemultiple design schemes of interleavers designed suitable for IDMA system were are proposed by domestic and foreign scholarsexperts.In this paper,varities ofous interleavers are classified and introduceddescribed.Then we make a comparison of the,advantages and disadvantages of various these interleaver design methods also compared.
