论文摘要
大型智能表面（LIS）概念最近成为无线通信，遥感和定位的新范式。它由一个连续的辐射表面组成，位于用户相对较近的位置，该表面能够通过独立的传输和接收（替换基站）与用户进行通信。尽管具有潜力，但从实现的角度来看，还有很多挑战，互连数据速率和计算复杂性是最相关的。预计分布式处理技术和分层体系结构将在确保可伸缩性的同时扮演至关重要的角色。在本文中，我们执行算法 - 建筑结构代码并分析硬件要求和架构权衡，以进行离散的LIS执行上行链路检测。通过这样做，我们希望为有效实施LIS系统提供具体的案例研究和指南。
The Large Intelligent Surface (LIS) concept has emerged recently as a new paradigm for wireless communication, remote sensing and positioning. It consists of a continuous radiating surface placed relatively close to the users, which is able to communicate with users by independent transmission and reception (replacing base stations). Despite of its potential, there are a lot of challenges from an implementation point of view, with the interconnection data-rate and computational complexity being the most relevant. Distributed processing techniques and hierarchical architectures are expected to play a vital role addressing this while ensuring scalability. In this paper we perform algorithm-architecture codesign and analyze the hardware requirements and architecture trade-offs for a discrete LIS to perform uplink detection. By doing this, we expect to give concrete case studies and guidelines for efficient implementation of LIS systems.
