Hybrid MIMO Architectures for Millimeter Wave Communications: Phase Shifters or Switches?
Roi Méndez-Rial, Cristian Rusu, Nuria González-Prelcic +2
Hybrid analog/digital MIMO architectures were recently proposed as an alternative for fully-digitalprecoding in millimeter wave (mmWave) wireless communication systems. This is mot…
An Overview of Signal Processing Techniques for Millimeter Wave MIMO Systems
Robert W. Heath, Nuria Gonzalez-Prelcic, Sundeep Rangan +2
Communication at millimeter wave (mmWave) frequencies is defining a new era of wireless communication. The mmWave band offers higher bandwidth communication channels versus those p…
Optimized Compressed Sensing via Incoherent Frames Designed by Convex Optimization
Cristian Rusu, Nuria González-Prelcic
The construction of highly incoherent frames, sequences of vectors placed on the unit hyper sphere of a finite dimensional Hilbert space with low correlation between them, has prov…
