Abstract

Generalized frequency division multiplexing (GFDM) is a promising non-orthogonal multicarrier transmission scheme which has recently received a great deal of attention towards future fifth generation (5G) wireless networks. It overcomes the limitations of orthogonal frequency division multiplexing (OFDM) while preserving most of the advantages of it. On the other hand, index modulation (IM) has the potential to provide a flexible system design with adjustable number of active subcarriers as well as significant bit error rate (BER) performance improvement for multicarrier systems. In this paper, we propose the combined application of GFDM and IM techniques. We present the GFDM-IM system model and evaluate its error performance by comparing to classical GFDM and OFDM-IM for Rayleigh multipath fading channels. It is shown via computer simulations that the GFDM-IM system achieves signicantly better error performance than classical GFDM due to the information bits carried in the spatial domain by the indices of active GFDM subcarriers.
