Abstract
Methods and devices for reducing undesired signals in a communication environment. At least two distinct composite signals (X and X ) are transmitted from a first communication environment ( ). A noise coefficient of the first communication environment ( ) based on the at least two distinct composite signals (X and X ) is calculated. At least two noise canceling signals based on the noise coefficient are calculated. The at least two noise canceling signals are added to an incoming signal (Y ) from a second communication environment ( ) to produce at least two combined signals. The at least two combined signal are transmitted into the first communication environment ( ).
