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: The objective of the proposed research is to provide a design guide on signal transmission and processing for millimeter-wave (mmWave) and Terahertz (THz) communications. Specifically, the higher-mmWave and THz bands, i.e., over 60 GHz, are investigated. Emerging communications over these new frequency bands with enormous bandwidth is a promising revolution for next-generation wireless systems. First, the difference between the higher-mmWave and THz bands and their lower-frequency counterparts is clarified. Then, an array-of-subarray architecture is designed to capture mmWave and THz channels while respect the nature of circuit hardware. Furthermore, fundamentals and performance of the array-of-subarray system for single-user communications are studied. Last but not least, a distance-aware multi-carrier transmission strategy is developed for multi-user wideband communications. As part of the proposed work, the strategies for beam training and channel estimation will be studied. Also, the relay-assisted transmission will be investigated to improve the connectivity and robustness of the system.
