Implementation of the software defined radio concept in terahertz range based on Wi-Fi

Principles of signal-code sequence (SCS) are examined. New methods and technical solutions are proposed to select the type of signal structures in order to achieve the best throughput and performance in wireless communication channel. The information efficiency criterion for channel resources usage is proposed based on the analysis of indicators and criteria that are recommended in the standard 802.11a/n to select specific SCS. Testing radio link on length 1.7 km is performed based on a wireless interface MikroTik R52n-M; the SCS is identified which was automatically selected by software defined radio (SDR) system for data transmission, and compared with SCS recommendations in standards 802.11 a/n. The telecommunication system based on Wi-Fi technology in a range of 130-134 GHz is developed, and tested in the laboratory with achieving data rates up to 1.2 Gbps.
