摘要:

智能反射面(IRS)由于能够通过控制传播环境来显著提高覆盖范围和频谱效率,被认为是下一代无线通信的潜在候选者。IRS提高频谱效率的方式之一是通过调整相移来执行无源波束成形。在这封信中,我们集成了IRS辅助通信的概念域的多方向波束成形,从而选择多个接收天线,以传达更多的信息比特比现有的空间调制(SM)技术在任何特定的时间。为了补充这个系统,我们还提出了一个连续的信号检测(SSD)技术在接收机。数值结果表明,所提出的设计能够提高系统传输的平均成功比特数(ASBT),优于文献中提出的其他最先进的方法。

英文摘要:

Intelligent reflecting surface (IRS) is being considered as a prospective candidate for next-generation wireless communication due to its ability to significantly improve coverage and spectral efficiency by controlling the propagation environment. One of the ways IRS increases spectral efficiency is by adjusting phase shifts to perform passive beamforming. In this letter, we integrate the concept of IRS-aided communication to the domain of multi-direction beamforming, whereby multiple receive antennas are selected to convey more information bits than existing spatial modulation (SM) techniques at any specific time. To complement this system, we also propose a successive signal detection (SSD) technique at the receiver. Numerical results show that the proposed design is able to improve the average successful bits transmitted (ASBT) by the system, which outperforms other state-of-the-art methods proposed in the literature.
