Massive MIMO and Waveform Design for 5th Generation Wireless Communication Systems

摘要

This article reviews existing related work and identifies the main challengesin the key 5G area at the intersection of waveform design and large-scalemultiple antenna systems, also known as Massive MIMO. The property ofself-equalization is introduced for Filter Bank Multicarrier (FBMC)-basedMassive MIMO, which can reduce the number of subcarriers required by thesystem. It is also shown that the blind channel tracking property of FBMC canbe used to address pilot contamination -- one of the main limiting factors ofMassive MIMO systems. Our findings shed light into and motivate for an entirelynew research line towards a better understanding of waveform design withemphasis on FBMC-based Massive MIMO networks.
