Method and apparatus for completely suppressing interference vectors in a DS-CDMA communication system (100). Receiver circuits (122, 124, 126, 128) are assigned (404, 406) to multipath from sectors both in soft handoff and not in soft handoff with the receiver. For each receiver circuit, a set of traffic channels present on the sector's signal is determined (410). For each receiver circuit, the interference is ranked (412) according to predetermined interference criteria. A set of interference vectors is selected (414) from the ranked lists of interference and an orthogonal projection is computed (416) of the receiver's desired code or Walsh code relative to the selected set of interference vectors. The receiver circuit then uses the orthogonal projection in its correlator to despread (418) received data.
