ABSTRACT:
This invention relates to telecommunications systems. In a subscriber loop carrying high speed data signals, noise cancellation is achieved by a data signal demodulator having first and second inputs 81,82, arranged to receive differential data signal and local field RFI input signals respectively. A feedback signal of the demodulator is sampled, processed, vector modulated and then combined with the local field RFI input signal of the demodulator. The combined signal is summed with the differential input signal to thereby reduce interference coupled with the first input.
