Abstract
A wireless network base station capable of canceling interference caused by a dominant interferer signal from a mobile station. The base station comprises down-converts an RF to a down-converted signal, r(n). K complex PN demodulators multiply the down-converted complex r(n) signal by PN code sequences associated with each of the K mobile stations to produce K chip streams. K Walsh code demodulators multiply each of the K chip streams by a Walsh code associated with a mobile stations to produce K raw user signals. K subtractors subtract a first estimated interference signal associated with the dominant interferer signal from the K raw user signals to produce K estimated user signals. A detector receives the K estimated user signals and produces a detected user signal for each of the mobile stations. An interference estimator then determines which detected user signal is the dominant interferer signal.
