A Novel Approach for Random Interleavers in IDMA System
نویسندگان
چکیده
Interleave Division Multiple Access (IDMA) is a multiuser scheme which enables user separation on the basis of interleavers. Interleaver design can allow the IDMA system to approach near Shannon limits of channel capacity. Interleaver combats against Intersymbol Interference (ISI), channel fading and all sorts of noises. In addition, interleavers provide security to the system users. Designing the random interleaver provides a solution for all impairments but they are generally considered computationally heavy. In this paper, an efficient approach has been developed for design of user specific random block interleavers. This design approach reduces the complexity for developing interleaving patterns and is computationally economical. Key-Words: Interleavers, Random Interleavers, Multiuser Detection, ISI, MAI, IDMA.

Interleave division multiple access (IDMA) scheme, uses interleavers for user separation. The selection of interleaver along with optimum design methodology for IDMA system leads to satisfactory results. An efficient interleaver must be easy to generate and should require low memory along with low correlation among interleavers. Existing Tree based interleaver has distinct advantage of low comp...

IDMA is being thought as a strong candidate for radio access in cellular mobile communication systems. It is attractive for wireless access because of its numerous advantages over TDMA, FDMA and CDMA. The InterleaveDivision Multiple-Access (IDMA) scheme is known for property of orthogonality amongst its user-specific interleavers. The interleavers are, therefore, referred has the heart of IDMA ...

In this paper we consider the design of practical interleavers for interleaver division multiple access (IDMA) systems. A set of interleavers is considered to be practical if it satisfies two criteria one it is easy to generate (i.e., the transmitter and receiver need not store or communicate many bits in order to agree upon an interleaver), and second no two interleavers in the set “collide”. ...
