PROCEDURE FOR REDUCING INTERFERENCE IN THE TRANSMISSION OF AN ELECTRICAL COMMUNICATION SIGNAL

摘要

Through crosstalk on lines, interference from current transmission lines or line echoes, the useable signal is superimposed by different interference signals. Th e task is to find a procedure for reducing interference which, compared to the cur rent state of the art, can be achieved with a smaller amount of computing input and i s suited to both the reduction of quasi steady-state and non-steady interference. In this, the interference of a received signal is classified with regards to charac teristics in the time range as a click, crackle, rumble or noise interference signal. The time range in which the interference occurs is marked. Depending on the interference type, interference blanking and/or an interpolation of the useable signal and/or a subtraction of the interference signal from the useable signal and/or a regenera tion of the useable signal is carried out.
