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。
In recent years, the Interleaver Division Multiple Access (IDMA) proposed by Professor Li Ping of the City University of Hong Kong has been extensively studied in various fields as a new multiple access technology. Interleaving Multiple access is based on different interleaver to distinguish between users, therefore, the design of interleaver IDMA system is a key technology. Many scholars have proposed a variety of interleaver designs for IDMA systems based on the traditional interleaver. The classification of design scheme of interleaver in IDMA system both at home and abroad is described and summarized, and the advantages and disadvantages of various interleaver design methods are compared.
