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…
Frequency Selective Hybrid Precoding for Limited Feedback Millimeter Wave Systems
Ahmed Alkhateeb, Robert W. Heath
Hybrid analog/digital precoding offers a compromise between hardware complexity and system performance in millimeter wave (mmWave) systems. This type of precoding allows mmWave sys…
Millimeter Wave Energy Harvesting
Talha Ahmed Khan, Ahmed Alkhateeb, Robert W. Heath
The millimeter wave (mmWave) band, which is a prime candidate for 5G cellular networks, seems attractive for wireless energy harvesting. This is because it will feature large anten…
Achievable Rates of Multi-User Millimeter Wave Systems with Hybrid Precoding
Ahmed Alkhateeb, Robert W. Heath, Geert Leus
Millimeter wave (mmWave) systems will likely employ large antenna arrays at both the transmitters and receivers. A natural application of antenna arrays is simultaneous transmissio…
