Abstract

The joint operation of two troposcatter digital stations (TSDS) of different modifications can be implemented quickly through an adaptive signal control in stations at the same time. Such control can be organized with the help of an adaptive simulation algorithm for tropospheric scatter link (TSL) by using TSDS1,2 and controlling the signals at the output and input of adaptive antennas (AdA), adaptive transmitters (AdT), and adaptive receivers (AdR) in each station. We used a modern digital troposcatter modem (DTM) of one station and adaptive signal processing based on a digital special-purpose control unit (DSCU) of another station. As a result, the adaptive signal control stabilizes the levels of tropospheric signals in both stations at the same time, which provides the regular information reliability of TSL with TSDS of different modifications in their joint work.
