Bit error rate analysis of various interleavers for IDMA scheme

摘要

One of the most popular and effective method adopted for the burst error control is to perform the interleaving operation before the transmission of data over a communication channel. In order to distribute the burst errors interleaver shuffles the sequence of original message bits. At the receiving end, the received message bits are re-shuffled to recover the message bits in its original sequence. Thus, the selection and designing of appropriate interleavers for an advanced multiple-access technique such as interleave-division multiple-access (IDMA) is always a key challenge. This paper presents the comparative performance analysis of various existing interleavers based on bit-error rate simulation considering the standard practical channel environment i.e. Additive White Gaussian Noise (AWGN) channel in the context of IDMA.
