There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

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.
