<p>An on-channel repeater having a receiving antenna, for receiving an RF signal to produce a received signal, a plurality of transmitting antennas, each for transmitting a respective transmitted signal, and a plurality of inputs, each for receiving a respective reference signal from each respective transmitted signal is provided. The transmitted signal comprises an amplified recovered signal derived from the received signal as well as a respective potentially interfering signal that may produce interference at the frequency of the received signal. A plurality of adaptive filters each coupled to a respective reference signal input are provided and controlled by a plurality of control coefficients to produce respective cancellation signals. A combiner then combines the cancellation and received signals to produce the recovered signal. A power amplifier is arranged to receive, amplify and transmit the recovered signal on each of the transmitting antennas.</p> |
