Double-Directional Channel Characterization of an Indoor Corridor Scenario at 300 GHz

The unique attributes and higher frequencies of the THz band (0.1–10 THz) make usage of channel models at lower frequencies impractical. Thus there is an acute need to develop new channel models to realize the potential of THz communication and extensive channel measurements can augment the pace of development. In this regard, a measurement conducted in an indoor corridor at 300 GHz using an in-house channel sounder is presented. The high-resolution three-dimensional measurement data are processed to obtain a double-directional angular delay power spectrum, and the delay and angular power profile to characterize the channel with regards to path loss, delay, and angular spreads. It is observed that the spread parameters are not only distance-dependent but are also influenced by the presence of natural reflectors in the measurement site. The evaluated results are further compared with other results in the literature at the same and lower frequencies. It is observed that while the spread parameters at lower frequencies reasonably agree with the current campaign the path loss values vary noticeably.
