Performance analysis of modified tent map interleaver in IDMA systems

In the last years, Interleave Division Multiple Access (IDMA) has been presented as a potential alternate of Code Division Multiple Access (CDMA) system. In IDMA systems, the interleavers are used to separate the users of the system in multiple access environments. Random interleaver is popular and basic taxonomy, which scrambles information bits of craving users with different patterns. Howeve...

Performance Analysis of Optimum Interleaver based on Prime Numbers for Multiuser Iterative IDMA Systems

In recently proposed multiple access techniques like IDMA and OFDM-IDMA, the user separation is done by user specific interleavers in contrast to the conventional CDMA scheme, where user separation is assured with user-specific signature sequences. The user specific interleavers must demonstrate minimum probability of collision amongst each other in addition to other merits, including minimal c...

User-specific chip-level interleaver design for IDMA systems

Introduction: The multiple access scheme recently studied in [1, 2] relies on interleaving as the only means for user separation, and hence it is referred to as interleave-division multiple-access (IDMA). IDMA not only inherits many advantages from conventional code-division multiple-access (CDMA), such as robustness against fading and mitigation of cross-cell interference, but also allows a ve...

Performance Analysis of Various Modulation Techniques in Multipath Ad-Hoc Network using Tree Based Interleaver for Iterative IDMA Systems

In recent years, the Interleave-Division Multiple-Access (IDMA) scheme has attracted the attention of researchers to be a promising candidate for next generation networks. And Since then numerous technical papers about IDMA have been published in the literature. In this paper, we have simulated the IDMA scheme with various interleavers and modulation mechanism to establish the fact that tree ba...

Performance Analysis of Idma Scheme Using Different Coding Techniques with Receiver Diversity Using Random Interleaver

In this paper performance analysis of IDMA systems is determined using different coding techniques. In this paper we use a receiver diversity approach which is useful in combating the fading in the IDMA scheme. In the transmitter section a single antenna is used where as in the receiver section two antennas are used. A comparative study has been performed between convolutional coding and zigzag...
