MIMO multi carrier interleave division multiple access system with multiuser detection

This paper provides the performance analysis of Multi Input Multi Output (MIMO) Multi carrier (MC) interleaver based multiple-access system with multiuser detection. Interleave-division multiple access (IDMA) is a scheme in which users are separated by employing different interleavers instead of different signatures as in a conventional code-division multiple-access (CDMA) scheme. The basic principle of IDMA is that the interleaver is different for different users. Interleavers are generated independently and randomly. At the receiver VBLAST/ZF/MAP detector is employed and its performance is analyzed for different channel conditions using an extensive simulation runs based on Monte Carlo simulation trials. Simulation results are provided to elucidate the benefits of IDMA scheme with multiuser detection.
