Massive MIMO Communications

Every new network generation needs to make a leap in area data throughput,
to manage the growing wireless data traffic. The Massive MIMO technology
can bring at least ten-fold improvements in area throughput by increasing the spectral
efficiency (bit/s/Hz/cell), while using the same bandwidth and density of base
stations as in current networks. These extraordinary gains are achieved by equipping
the base stations with arrays of a hundred antennas to enable spatial multiplexing
of tens of user terminals. This chapter explains the basic motivations and communication
theory behind the Massive MIMO technology, and provides implementationrelated
design guidelines
