ABSTRACT:
A repeater and methods thereof are provided. The example repeater first receives a donor signal (e.g., from a base station for repeating in a downlink direction, from a mobile station for repeating in an uplink direction, etc.) and a transmitted version of an internally generated pilot signal. The repeater configures an adaptive filter signal to cancel the received transmitted version of the internally generated pilot signal. In an example, the first receiving and configuring steps may be performed during a first mode of operation (e.g., a “training” mode). The repeater second receives the donor signal and a retransmitted version of the donor signal (e.g., retransmitted from the repeater). The repeater cancels the retransmitted donor signal based on the configured adaptive filter signal.
