FIELD: information technology. ^ SUBSTANCE: apparatus for suppressing intermodulation interference has a reconstruction circuit adapted to receive a transmitted signal, approximate linear and nonlinear characteristics of the leakage channel from the transmitting device to the receiving device, determine normalisation based on the predicted power level of the transmitted signal during analogue-to-digital conversion in the leakage channel and provide a reconstructed output signal; and a signal adder which can subtract the reconstructed signal from the signal coming from the receiving device. ^ EFFECT: high efficiency of suppressing intermodulation interference in a receiving device. ^ 32 cl, 9 dwg |
