This research paper delves into the level of development and advantages of application oftelecommunication systems of terahertz range (100GHz to 3000GHz), including the fields ofapplication for the developed technologies as well as the outstanding problems and feasible methods of their solution. Unfortunately, the frequency resource of the currently used radio-frequency band is physically incapable of transmitting very high-speed and high-speed data torrents via a radio channel. The application of multilevel modulations that could allow for the increase in speed is rather limited whereas the application of higher frequencies allows for theuse of broader frequency band to transfer the gigabit torrents. This innovative approach hasmany advantages, in particular, confidentiality of data transmission and narrow-beam radio emission. This paper also gives examples of available systems using the state-of-the-art semiconductor CMOS, SiGe and GaAs technologies and it also describes their specific features. © 2011 by Begell House, Inc.

The results of development of the transceiver for 130-134 GHz band digital radio relay system are provided. The transceiver power amounted to 10 dBm, the receiver sensitivity was of about 10-11 W. Under the conditions of QAM-256 modulation the bit rate of 150 Mbps has been attained within the IF bandwidth of 25 MHz. © 2013 by Begell House, Inc. Source

The present paper discloses that the system of matrices for orthogonal skew-symmetric anticommuting operators is apt to generate a Clifford algebra representation in terms of matrices. The statistical properties of this particular system of operators as applied to a random vector have been examined. The operator system obtained is feasible for producing a set of orthogonal signals in the multiple-access noise-signal communication system. © 2013 by Begell House, Inc. Source
