Abstract
Methods and devices for reducing undesired signals in a communication environment. At least two distinct composite signals (X.sub.1 and X.sub.2) are transmitted from a first communication environment (260). A noise coefficient of the first communication environment (260) based on the at least two distinct composite signals (X.sub.1 and X.sub.2) 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.sub.3) from a second communication environment (280) to produce at least two combined signals. The at least two combined signal are transmitted into the first communication environment (260).
Claims6
A method for reducing an undesired signal in a first communication environment comprising:
- transmitting at least two distinct composite signals to a second communication environment;
- calculating a noise coefficient of the first communication environment based on a portion of the at least two distinct composite signals;
- calculating at least two noise canceling signals based on the noise coefficient;
- and
- adding the at least two noise canceling signals to an incoming signal from the second communication environment to produce at least two combined signals.
A method of reducing an undesired signal in a first communication environment comprising the steps of:
- receiving at least two distinct composite signals from the first communication environment;
- separating each of the at least two distinct composite signals into a desired signal and an undesired signal;
- generating at least two canceling signals based on an inverse of the undesired signal;
- combining the at least two canceling signal with an incoming signal from a second communication environment to create at least two combined signals;
- and
- transmitting the at least two combined signals into the first communication environment.
A method of reducing an undesired signal in a communication environment comprising the steps of:
- transmitting at least two distinct composite signals;
- generating at least two canceling signals based on one of the at least two composite signal;
- combining the at least two canceling signals with an incoming signal to form at least two output signals;
- and
- introducing the at least two output signals into the communication environment.
