Analysis and design of tent map interleaver for interleave division multiple access scheme

Abstract

Interleavers are the main component of almost all multiple access systems, such as Code Division Multiple Access (CDMA) and Interleave Division Multiple Access (IDMA henceforth). In IDMA systems, interleavers are crucially important for user separation that consequently also contributes maximising the system throughput. The paper intends to claim an efficient Tent map based design of interleaver (TMI henceforth) generation which has less computational complexity and is more efficient in bandwidth compared to the existing prevailing algorithms in the domain. The proposed scheme is based on chaos theory and the simulation results show that TMI based IDMA can achieve the good BER performance without the need of extra memory resources.
