<p>A multipath interference cancellation method in a multicode code division multiple access (cdma) system comprising a transmitter and a receiver is disclosed. The method is for determining, at the receiver, a set of data symbols of a multicode signal transmitted from the transmitter. The transmitted multicode signal propagates along multiple paths as respective multipath components. These multipath components are received by the receiver as a composite signal from which the set of data symbols of the multicode signal is obtained. The method includes estimating each multipath component, path by path, based on a modified composite signal. The modified composite signal is the result of subtracting a sum of previously estimated multipath components, if any, from the composite signal. The method further includes estimating the set of data symbols of the multicode signal based on the estimated multipath components. A receiver wherein the method is implemented is also disclosed.</p> |
