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.
