Performance Analysis of Large Intelligent Surfaces (LISs): Asymptotic Data Rate and Channel Hardening Effects

Understand

The concept of a large intelligent surface (LIS) has recently emerged as a promising wireless communication paradigm that can exploit the entire surface of man-made structures for transmitting and receiving information.

• An LIS is expected to go beyond massive multiple-input multiple-output (MIMO) system, insofar as the desired channel can be modeled as a perfect line-of-sight.
• To understand the fundamental performance benefits, it is imperative to analyze its achievable data rate, under practical LIS environments and limitations.
• In this paper, an asymptotic analysis of the uplink data rate in an LIS-based large antenna-array system is presented.
