  2. 1. On Massive MIMO Base Stations with Low-End Hardware

    Author : Christopher Mollén; Erik G. Larsson; Thomas Eriksson; Josef Nossek; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; massive MIMO; hardware; ADC; power amplifier; out-of-band radiation; peak-to-average ratio;

    Abstract : Massive MIMO (Multiple-Input Multiple-Output) base stations have proven, both in theory and in practice, to possess many of the qualities that future wireless communication systems will require.  They can provide equally high data rates throughout their coverage area and can concurrently serve multiple low-end handsets without requiring wider spectrum, denser base station deployment or significantly more power than current base stations.
