Efficient Beam Alignment in Millimeter Wave Systems Using Contextual Bandits
Morteza Hashemi, Ashutosh Sabharwal, C. Emre Koksal +1
In this paper, we investigate the problem of beam alignment in millimeter wave (mmWave) systems, and design an optimal algorithm to reduce the overhead. Specifically, due to direct…
Linear Block Coding for Efficient Beam Discovery in Millimeter Wave Communication Networks
Yahia Shabara, C. Emre Koksal, Eylem Ekici
The surge in mobile broadband data demands is expected to surpass the available spectrum capacity below 6 GHz. This expectation has prompted the exploration of millimeter wave (mm-…
Energy-Efficient Power and Bandwidth Allocation in an Integrated Sub-6 GHz -- Millimeter Wave System
Morteza Hashemi, C. Emre Koksal, Ness B. Shroff
In mobile millimeter wave (mmWave) systems, energy is a scarce resource due to the large losses in the channel and high energy usage by analog-to-digital converters (ADC), which sc…
Fast Analog Beam Tracking in Phased Antenna Arrays: Theory and Performance
Jiahui Li, Yin Sun, Limin Xiao +2
The directionality of millimeter-wave (mmWave) communications introduces a significant challenge in serving fast-rotating/moving terminals, e.g., mobile AR/VR, high-speed vehicles,…
Analog Beam Tracking in Linear Antenna Arrays: Convergence, Optimality, and Performance
Jiahui Li, Yin Sun, Limin Xiao +2
