Echo compensation for the German communications satellite
Abstract
Research with the aim of realizing echo compensators for time-variable systems for the German communications satellite is reported. The principle of satellite connection with echo compensators is discussed and the mode of operation of known compensators for time-invariant systems is described. The time-variable system structure of echo series in two-wire telecommunications systems is addressed along with the structure of an echo compensator for identifying and reproducing such systems. Finally, first simulation results for identifying purely time-variable echo series transmission functions are reported.
