Architectures and Models for Advanced MIMO Systems

MIMO communication remains an important technology for wireless communication systems. In this tutorial, we revisit classical signal processing models for MIMO wireless communications. We consider how those models may be updated as MIMO systems go to higher carrier frequencies, broader bandwidths and new kinds of array architectures. Through these updates, we revisit concepts from antennas, circuits and array processing including impedance, broadband arrays, beam squint, mutual coupling and polarization.
