Exploiting iterative demapping and decoding for multiple access

Abstract

We exploit the IDD for multiple access in this thesis and provide a variety of MATLAB software-based simulation results to demonstrate the advantage of the new multiple access technique over the conventional ones such as TDMA, FDMA, CDMA, etc., in which multiple users share system resources for communications under a certain degree of wastefulness (e.g. each user only uses a fraction of time (for TDMA), or a fraction of allocated transmission bandwidth (for FDMA), or all time and allocated bandwidth but very large used bandwidth (for CDMA)).

Keywords: multiple access, iterative decoding and demapping, interleaver, modulation, fading channel, multi-user detection.
