Multiple input, multiple output (MIMO) refers to systems using multiple antennas (and correspondingly multiple channels) to transmit and receive information. MIMO is a form of spatial diversity, which ...

The world has gone wireless. From mobile phones to the latest tablet computers, mobility is a key feature, and there are many different ways to provide wireless data. The demand for higher data rates ...

Abstract: Distinguishing the near-field and far-field regions in line-of-sight (LoS) multiple-input multiple-output (MIMO) systems is crucial, as their distinct characteristics significantly impact ...

In the first installment of this series, “The MIMO advantage,” I covered the basics of multiple input, multiple output (MIMO). In this installment, I’ll provide the high-level calculations for ...

Abstract: Thanks to low path-loss and high macro-diversity gain, the cell-free (CF) massive multiple-input multiple-output (MIMO) is regarded as a perspective technique to realize ultra-reliable and ...
