SYSTEMS AND METHOD FOR CANCELING FEEDBACK INTERFERENCE |
摘要 |
The present application discloses systems and methods for reducing output-to- input feedback signal interference caused by a forwarding node that is configured to forward information received from a transmitter. In some embodiments, this output-to- input feedback signal interference is compensated for by the transmitter. For example, the transmitter is configured such that the signal that is transmitted by transmitter to the forwarding node includes both (1) a primary signal or 'desired' signal (e.g., the signal that is intended for a receiving device) and (2) a filtered version of the primary signal. The filter that produces the filtered version of the primary signal is configured (e.g., the filter's filter weights are adapted) such that the filtered version of the primary signal cancels or reduces the undesired output-to-input feedback signal. |
