[EN] The use of massive multiple-input multiple-output (MIMO) techniques for communication
at millimeter-Wave (mmW) frequency bands has become a key enabler to meet the data rate demands
of the upcoming fifth generation ...

[EN] This paper presents a meaningful practical performance comparison between the last generation
of Graphics Processing Units (GPUs) and the last generation multi-core CPUs when they are
used to solve given Signal ...
