Abstract

three-dimensional modulation using beam hopping (3DModBH), which is a novel transmission scheme, is employed for small cell indices and two-dimensional (2-D) modulation techniques to convey the information. 3DModBH in practical interference-limited scenario in 5G systems is not yet considered. In this paper, 3DModBH in interference-limited scenario is investigated. The joint maximum likelihood (JML) receiver can be applied to retrieve the transmitted bits. However, its complexity is prohibited for practical implementation. Therefore, we suggest novel and reduced complexity receivers for 3DModBH in interference-limited scenario. Simulation results show that the proposed receiver algorithms with 3DModBH are capable of performing almost optimal performance as the 3DModBH with JML receiver, significantly outperforming the state-of-theart transmission scheme (SoAT) with JML receiver and reducing in computational complexity compared with JML receiver.

5G系统中采用波束跳变的三维调制接收机的降低复杂度

利用跳波束三维调制(3DModBH)是一种新颖的传输方案，利用小小区指数和二维(2-D)调制技术传输信息。目前还没有考虑3DModBH在5G系统实际干扰限制场景中的应用。本文研究了3DModBH在干扰限制情况下的应用。联合最大似然(JML)接收机可用于检索发送的比特。然而，它的复杂性在实际实现中是被禁止的。因此，我们建议在干扰有限的情况下为3DModBH提供新颖且降低复杂性的接收器。仿真结果表明，采用3DModBH的接收端算法与采用JML接收端的3DModBH算法相比具有几乎最优的性能，显著优于采用JML接收端的状态传输方案(SoAT)，且与采用JML接收端的方案相比计算复杂度有所降低。
