Uplink and Downlink Transceiver Design for OFDM with Index Modulation in Multi-user Networks

A new modulation scheme called OFDM with
index modulation (OFDM-IM) is introduced recently. This
scheme allows to transmit additional bits by mapping
a part of incoming bit stream to the indices of the
subcarriers. In this work, performance of OFDM-IM in
multi-user networks for uplink and downlink scenario is
studied. For both scenarios, novel base station designs are
introduced in order to overcome the inter-user-interference
(IUI). Simulation results show that OFDM-IM outperforms
the classical OFDM in multi-user networks and IUI is
eliminated successfully even in large networks.
