摘要：
A method for estimating a feedback channel for a wireless repeater detects changes in a power of a remote signal. When a large power swing in the remote signal is detected, the method operates to discard samples or blocks of samples of the pilot and receive signals and a final channel estimate is generated using undiscarded samples of the pilot and receive signals. Alternately, sub channel estimates are generated using individual blocks of the pilot samples and receive samples. When a large power swing in the remote signal is detected, the method operates to discard one or more sub channel estimates and a final channel estimate is generated using undiscarded sub channel estimates.
