Decentralized equalizer construction for large intelligent surfaces

Alegria, Juan Vidal LU orcid ; Rodriguez Sanchez, Jesus LU ; Rusek, Fredrik LU ; Liu, Liang LU orcid and Edfors, Ove LU orcid (2019) 90th IEEE Vehicular Technology Conference, VTC 2019 Fall In IEEE Vehicular Technology Conference 2019-September.
Abstract

In this paper we present fully decentralized methods for calculating an approximate zero- forzing (ZF) equalizer in a large intelligent surface (LIS). A LIS is intended for wireless communication and facilitates unprecedented MU- MIMO performance, far superior to that of Massive MIMO. Antenna modules in the grid connect to their neighbors to exchange messages of information needed for interference cancellation in a fully- decentralized fashion, making the system scalable. By a careful design of how the messages are routed, we show that the proposed method is able to cancel inter-user interference sufficiently well without any centralized coordination, opening the door for the realization of this type of structures.
