Progressive pattern orthogonal interleaver set for interleave division multiple access based, non orthogonal multiple access schemes: Beyond 5G perspective

Abstract This communication suggests an orthogonal interleaver set for interleave division multiple access (IDMA) based non (NOMA) schemes from beyond 5G viewpoint to support enormous increase in user count. The method generates by providing two mother interleavers as seed generate other users’ interleaving patterns progressively. key feature of the proposed scheme is that it reduces implementation complexity and memory requirement at base station, while implementing iterative multiuser detection (MUD), which most interlaever designs suggested literature do not consider. It provides additional security data due progressively changing interleavers’ pattern along with conventional purpose unique identity individual users system. tested through simulations under IDMA system configurations. has been observed preserves bit error rate (BER) performance optimal minimal information exchange between station mobile share design.
