Comparative Analysis of 5G Multicarrier Techniques with Index Modulation

In the last two decades, the wireless communications field has seen many radical disruptions in improving technologies. It is to provide the highest quality of service to the end-user. Fourth-generation wireless communications technology is one of this kind. Currently, Fifth-generation (5G) wireless communications network is the much-anticipated technology to serve massive bandwidth efficiency. This technology gives a stable platform to many state-of-the-art technologies regarding their need for reduced latency communication purposes. The applications of this technology are used in the fields of critical healthcare services, autonomous driving and smart homes etc. The existing technology has shown some intriguing trade-off among the requirements for 5G. Generalised Frequency Division Multiplexing (GFDM) and Filter Bank Multicarrier (FBMC) are the potential schemes that satisfy the needs of the 5G networks. On the other hand, Index Modulation (IM) provides the modular architecture and the BER efficiency for the multicarrier systems. The aforementioned potential schemes, when combined with IM, open for new possibilities. The proposed research work is mainly focused on the applications of the GFDM-IM and FBMC-IM. Under the Rayleigh multipath fading channel and Additive White Gaussian Noise channel (AWGN), this research work presents the GFDM-IM and FBMC-IM device models. These models are then compared with GFDM-QAM, FBMC-OQAM, and OFDM-IM in terms of error performance without compromising the requirements of 5G.
