Abstract
A wireless repeater includes an echo canceller to cancel an estimated feedback amount from an input signal and a reference receiver to sample a portion of the transmit signal prior to over-the-air transmission for use as the reference signal for channel estimation. More accurate channel estimation is obtained by using the reference signal from the reference receiver as the reference signal accounts for distortions in the transmitter circuit of the repeater.
