Abstract:

Millimeter-wave and Terahertz communications are envisioned as a key technology for next-generation wireless systems.  The objective of the thesis is to provide a design guide on signal transmission and processing for millimeter-wave and Terahertz communications. Specifically, the higher-millimeter-wave and Terahertz bands, i.e., over 60 GHz, are investigated. First of all, the array-of-subarrays architecture is investigated from system power consumption, spectral efficiency, and energy efficiency to shows its advantages. Second, we further study the subarray-based coordinated beamforming training with multi-resolution time-delay codebooks for the millimeter-wave and Terahertz systems. Third, fundamental performance limits and optimized array design of the array-of-subarrays system for single-user communications are studied. Last but not least, a distance-aware multi-carrier transmission strategy is developed for multiuser wideband communications. In summary, the proposed design in this thesis builds the physical-layer foundation for higher-millimeter-wave and Terahertz communications.
