“…Several works focus on the receiver side. [17] and [18] reduce the receiver complexity by employing frequency domain processing. In addition, different techniques have been adopted to achieve low-complexity receiver implementation, such as sparsification and block diagonalization [19], Taylor series and conjugate gradient [20], and tabu search [21].…”

<div>As a candidate waveform for next-generation wireless communications, generalized frequency division multiplexing (GFDM) features several decent properties which make it promising. In this paper, we systematically overview the research about GFDM. We start with GFDM transceivers with their main components, which consist of prototype ﬁlter design, low-complexity transceiver implementation, and symbol detection algorithms. Then, we investigate a couple of non-ideal issues of GFDM, including synchronization issues, channel estimation, and in-phase/quadrature (I/Q) imbalance compensation. Lastly, we study the applications of GFDM-based cognitive radio and full-duplex radio which boast of a high spectral efﬁciency.</div>

“…It is now possible to implement flexible GFDM modems with a complexity similar to the one achieved by conventional OFDM implementations [36]. An efficient Zero-Forcing (ZF) receiver implementation for FSCs is proposed in [37]. These simplifications in the GFDM implementations allows this waveform to be used by B5G networks with insignificant impact on the overall cost of the terminals.…”

“…Alternatively, the linear detectors, including linear zero forcing (ZF) detector and minimum mean square error (MMSE) reduced the complexity. However, the specific realization of the channel has a great impact on their detection performance 30 . But the detectors reported so far will perform worse for MIMO‐GFDM approach with precoding methods.…”

Nowadays, wireless accesses are demanded with new applications, but they generate many technical issues. Moreover, the issues related to the beyond fifth generation (5G) wireless networks can be tackled using an orthogonal frequency division multiplexing (OFDM) schemes. Due to the huge growth of wireless users, this scheme exists with some technical challenges. An enhanced radio access technology is required to tackle the technical constraints of upcoming 5G wireless network applications. Nowadays, the generalized frequency division multiplexing (GFDM) scheme is exploited by wireless networks because of their benefits like spectral efficiency, low latency, and out-of-band (OOB) emission. In this paper, a linear constellation precoded GFDM with interleaved quadrature index modulation (LCP-GFDM-IQIM) scheme is proposed to harvest extra diversity gain by spreading the information symbols in-phase/quadrature component. Also, in-phase/quadrature (I and Q) dimensions are explored in index modulation (IM). Both theoretical and simulation analysis shows that the proposed LCP-GFDM-IQIM scheme achieves better spectral efficiency and energy efficiency as compared to the existing methods.
