Impulse Ultrawideband Wireless Communication System of the Terahertz Frequency Band

The paper considers the possibility of developing a wireless telecommunication system of the terahertz band (THz), in which a impulse radio ultrawideband signal (IR-UWB) is used as an information carrier. Variant of the of transmission and reception paths construction of THz IR-UWB wireless communication system (WCS) are considered, taking into account the technical characteristics of the THz devices available on the telecommunications market.The one of the main results is the block diagram of the IRUWB WCS of the terahertz range development of the point-to-point type based on the heterodyning method. It is also important that already existing technical implementations of some THz blocks (subharmonic mixer, waveguides, antennas etc.) of the transmitter and receiver devices, which allows to determine which devices of the WCS require designing.The calculation of the energy budget of the THz IR-UWB WCS line for various types of the IR-UWB signal modulation was also carried out, which made it possible to estimate the distance between corresponding stations under different conditions of the electromagnetic wave propagation environment.
