Millimeter-wave frequencies offer abundant spectrum and high data rates, but their use comes at the cost of a severe propagation loss. The loss can be alleviated by establishing directional communication links with high beamforming gains between the base stations and users and by using dense network deployments. Beam training is a procedure that reveals the best beam steering directions in a wireless channel. When performed with conventional phased arrays that have many antenna elements, beam training imposes a large overhead. In this work, we introduce true-time-delay array architectures as promising alternatives for phased arrays to solve the overhead problem. Compared to phased arrays, true-time-delay arrays can synthesize frequency-dependent beams and thus probe all angular directions simultaneously using different signal frequencies. We leverage this property to develop and analyze low-complexity digital signal processing algorithms for fast and accurate millimeter-wave beam training. Unlike beam training, channel estimation has the goal to estimate all parameters of a sparse millimeter-wave channel. We exploit the channel sparsity and frequency-dependent beams of true-time-delay arrays to develop a frequency-domain compressive sensing based algorithm for channel estimation. We also analyze the performance of the developed algorithm in the presence of practical hardware impairments and we derive the lower bounds on the variances of channel parameter estimators. In dense millimeter-wave networks with a small inter-site distance and a large number of users, directional beams can cause significant interference and prevent data-hungry users from satisfying their rate requirements. The user experience and the overall network performance can be optimized through coordinated user association and beam scheduling on a network level. Given the channel estimates between different pairs of base stations and users, we develop and analyze a new multi-step optimization framework for joint user association and beam scheduling. The main goal of the framework is to maximize the number of users with satisfied rate requirements while simultaneously suppressing the inter- and intra-cell interference. Since the framework includes NP-hard optimization problems, we propose an algorithm that attains a sub-optimal solution in polynomial-time.

Millimeter wave (mmWave) has the potential to provide vehicles with high data rate communications that will enable a whole new range of applications. Its use, however, is not straightforward due to its challenging propagation characteristics. One approach to overcome the propagation challenge is the use of directional beams, but it requires a proper alignment and presents a challenging engineering problem, especially under the high vehicular mobility. In this dissertation, fast and efficient beam alignment solutions suitable for vehicular applications are developed. To better quantify the problem, first the impact of directional beams on the temporal variation of the channels is investigated theoretically. The proposed model includes both the Doppler effect and the pointing error due to mobility. The channel coherence time is derived, and a new concept called the beam coherence time is proposed for capturing the overhead of mmWave beam alignment. Next, an efficient learning-based beam alignment framework is proposed. The core of this framework is the beam pair selection methods that use side information (position in this case) and past beam measurements to identify promising beam directions and eliminate unnecessary beam training. Three offline learning methods for beam pair selection are proposed: two statistics-based and one machine learning-based methods. The two statistical learning methods consist of a heuristic and an optimal selection that minimizes the misalignment probability. The third one uses a learning-to-rank approach from the recommender system literature. The proposed approach shows an order of magnitude lower overhead than existing standard (IEEE 802.11ad) enabling it to support large arrays at high speed. Finally, an online version of the optimal statistical learning method is developed. The solution is based on the upper confidence bound algorithm with a newly introduced risk-aware feature that helps avoid severe misalignment during the learning. Along with the online beam pair selection, an online beam pair refinement is also proposed for learning to adapt the codebook to the environment to further maximize the beamforming gain. The combined solution shows a fast learning behavior that can quickly achieve positive gain over the exhaustive search on the original (and unrefined) codebook. The results show that side information can help reduce mmWave link configuration overhead.

This book comprehensively reviews the state of the art in millimeter-wave antennas, traces important recent developments and provides information on a wide range of antenna configurations and applications. While fundamental theoretical aspects are discussed whenever necessary, the book primarily focuses on design principles and concepts, manufacture, measurement techniques, and practical results. Each of the various antenna types scalable to millimeter-wave dimensions is considered individually, with coverage of leaky-wave and surface-wave antennas, printed antennas, integrated antennas, and reflector and lens systems. The final two chapters address the subject from a systems perspective, providing an overview of supporting circuitry and examining in detail diverse millimeter-wave applications, including high-speed wireless communications, radio astronomy, and radar. The vast amount of information now available on millimeter-wave systems can be daunting for researchers and designers entering the field. This book offers readers essential guidance, helping them to gain a thorough understanding based on the most recent research findings and serving as a sound basis for informed decision-making.
