Transmission Through Large Intelligent Surfaces: A New Frontier in Wireless Communications

Ertugrul Basar

摘要:

在本文中,传输通过大智能表面(LIS),故意修改入射波的相位,以提高在接收器的信号质量,提出了作为未来的无线通信系统和标准的一个有前途的候选人。对于所考虑的LIS辅助系统,一个通用的数学框架,推导出的接收信号噪声比(SNR)的分布的符号错误概率(SEP)的计算。接下来,提出了使用LIS本身作为接入点(AP)的新概念。广泛的计算机仿真结果提供评估的潜力LIS为基础的传输,其中LIS作为一个智能反射器或AP与或不知道信道相位。我们的研究结果表明,基于LIS的通信可以成为未来无线系统的一个改变游戏规则的范例。

英文摘要:

In this paper, transmission through large intelligent surfaces (LIS) that intentionally modify the phases of incident waves to improve the signal quality at the receiver, is put forward as a promising candidate for future wireless communication systems and standards. For the considered LIS-assisted system, a general mathematical framework is presented for the calculation of symbol error probability (SEP) by deriving the distribution of the received signal-to-noise ratio (SNR). Next, the new concept of using the LIS itself as an access point (AP) is proposed. Extensive computer simulation results are provided to assess the potential of LIS-based transmission, in which the LIS acts either as an intelligent reflector or an AP with or without the knowledge of channel phases. Our findings reveal that LIS-based communications can become a game-changing paradigm for future wireless systems.
