Adaptive Simulation Algorithm for Tropospheric Scatters Link with Two Troposcatter Communication Stations of Different Modifications

The joint work of two troposcatter digital stations (TSDS) of different modification can be implemented quickly through adaptive signal control in both 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 TSDS and controlling the signals at the output 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 control of signals 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.
