Data signals for Terahertz communications research

The Terahertz (THz) band (0.1–10 THz) is a key asset to unlock the next generation of wireless communication systems. With larger available bandwidths, THz systems would allow for faster data rates to interconnect many more users than traditional communication systems in the microwave and millimeter wave frequency ranges. While the hardware for THz communications is quickly emerging, the wireless research community lacks access to THz signals. In addition to hardware solutions, much is left to explore on the signal processing side for THz communications. Thus, in this paper, an extensive data set consisting of 260 frames of information-carrying ultrabroadband signals transmitted and received at 120–140 GHz, 210–240 GHz, and 1–1.05 THz is presented. This data set will enable the wireless community to experimentally explore solutions relating to ultrabroadband time, frequency and phase synchronization, channel estimation and equalization, and modulation, to name a few.
