ABSTRACT:
A data modulated carrier is branched into two orthogonal components and as a result of correlation with a difference signal supplied to a receiver, first and second regulating signals are produced. The first and second regulating signals each regulate a base band simulation stage to produce respective dummy signals, taking into account the two orthogonal signal components, and form components of a compensation signal which is used to suppress a cross-talk signal which is superimposed on a signal received from a remote station.
