THz & mmWave Communications

THz & mmWave communication is a critical component for 6G wireless systems, heralding significant advancements in data rate. The THz band offers vast unexploited bandwidth that can support the transmission of data at multi-gigabit or even terabit per second speeds. However, this promising potential is not without its challenges: Large propagation loss, hardware constraints, and severe blockage. To mitigate these issues, many interesting ideas such as cooperative communication strategies, RIS, and hybrid beamforming are exploited.
