ABSTRACT:

The massive antenna array is one of the key technologies to enable  mm-wave communications for 5G and beyond. Unfortunately, the  implementation of full massive MIMO arrays proved to be too costly and  unnecessary, and the wireless industry is adopting hybrid antenna  arrays as a practical approach going forward. Based on our pioneering  work on hybrid antenna arrays reported nearly a decade ago, we shall  present our recent research on new massive hybrid array architectures.  These include hybrid antenna arrays of localized phased arrays,  lenses, Butler matrices and reconfigurable Butler matrices. We shall  report new signal processing algorithms for angle of arrival (AoA)  estimation and beam synthesis to support these hybrid array  architectures. A comparison on the power consumption of these  different hybrid beamforming architectures will also be reported.
