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.

5G异构无线网络中带有索引调制的高效线性星座预编码广义频分复用的性能分析

如今,新的应用程序要求无线访问,但是它们会产生许多技术问题。此外,可以使用正交频分复用(OFDM)方案解决与第五代(5G)无线网络相关的问题。由于无线用户的巨大增长,该方案存在一些技术挑战。需要一种增强的无线电接入技术来解决即将到来的5G无线网络应用的技术限制。如今,通用频分复用(GFDM)方案因其诸如频谱效率,低延迟和带外(OOB)发射等优点而被无线网络采用。在本文中,提出了一种采用交错正交索引调制(LCP‐GFDM‐IQIM)方案的线性星座预编码GFDM,以通过扩展同相/正交分量的信息符号来收获额外的分集增益。同样,在索引调制(IM)中探索了同相/正交(I和Q)维度。理论和仿真分析均表明,与现有方法相比,所提出的LCP-GFDM-IQIM方案具有更好的频谱效率和能效。
