Query: Massive MIMO and Waveform Design for 5th Generation Wireless
  Communication Systems   This article reviews existing related work and identifies the main challenges
in the key 5G area at the intersection of waveform design and large-scale
multiple antenna systems, also known as Massive MIMO. The property of
self-equalization is introduced for Filter Bank Multicarrier (FBMC)-based
Massive MIMO, which can reduce the number of subcarriers required by the
system. It is also shown that the blind channel tracking property of FBMC can
be used to address pilot contamination -- one of the main limiting factors of
Massive MIMO systems. Our findings shed light into and motivate for an entirely
new research line towards a better understanding of waveform design with
emphasis on FBMC-based Massive MIMO networks.
