Abstract
The invention is a device and a method for cancelling interferences between signals with frequency proximity, inherent to the co-location of multi-standard terminals, in a communication system. The interfering signal is sampled either on the interfering signal or on the disturbed signal then phase shifted and attenuated according to the level of the disturbance and summed with the disturbed signal, so forming a neutralizing loop that can cancel the disturbance

Method of cancelling interferences between signals with frequency proximity, inherent to the co-location of multi-standard terminals, in a communication system, wherein the method comprises the steps of:
- taking a sample, by coupling, of an interfering signal emitted towards a first terminal, and forming a loop for neutralizing this signal on the disturbed signal, received by one of the second terminals according to an indication signifying the disturbance level due to this interfering signal.
Device for cancelling interferences between signals with frequency proximity, inherent to the co-location of multi-standard terminals in a communication system, wherein it comprises:
- a coupling element for taking a sample of a signal, emitted towards a first terminal, that is the source of interferences on a signal received by one of the other terminals;
- elements forming a neutralizing loop on the received signal from the interference-source signal, the loop being controlled by a signal indicating the disturbance level due to this interfering signal.
