Terahertz band: Analysis of sounding bandwidth and center frequency on power delay profile model

This paper investigates the impact of different sounding bandwidths and center frequencies on power delay profile (PDP) at Terahertz (THz) band based on ray-tracing simulations. The effect of transmit power is also investigated for the center frequencies 300 GHz and 1500 GHz. This approach is based on complex frequency responses extracted for the Transmitter (Tx) and Receiver (Rx) pair, 10 m apart in Line of Sight (LoS) scenario. An accurate 3D model of the office environment has been modeled considering real-world parameters. By evaluating the optimal bandwidth and center frequency, one can construct the precise ultra-broadband terahertz channel models. Such characterization would allow the system designer to deal with trade-offs between performance and complexity when the optimal operating bandwidth and the corresponding center frequency are formerly known. It is also of great significance nowadays to explore Terahertz band for parametrization and standardization of future wireless systems.
