Abstract: A noise reduction system in a wireless communication network, including: two or more input antennas adapted to receive wireless signals; wherein each input antenna has a different receiving characteristic, so that the signals provided by the input antennas constitute a distinct combination of the received signals; a filter coupled to each of the input antennas except one, wherein the filter is adapted to estimate the correlation between the signal provided by its associated input antenna and the signal provided by the input antenna not coupled to a filter and mitigate a dominant component of the received signals responsive to the estimation; a summator that is adapted to combine the filtered signal and the signal provided by the input antenna not coupled to a filter and provide the result as feedback to the filter; and wherein the filtered signals from all the filters are combined to form an output signal.
