A spread-spectrum CDMA interference canceler for reducing interference in a DS/CDMA receiver having N chip-code channels. The interference canceler includes a plurality of correlators, a plurality of spread-spectrum-processing circuits, subtracting circuits, and channel correlators. Using a plurality of chip- code signals generated from chip codeword signal generators, the correlators despreads the spread-spectrum CDMA signal as a plurality of despread signals. The plurality of spread-spectrum-processing circuits uses a timed version of the plurality of chip-code signals generated from the delay devices, for spread- spectrum processing the plurality of despread signals. For recovering a code channel using an i th chip-code-signal, the subtracting circuits subtracts from the spread-spectrum CDMA signal, each of the N-1 spread-spectrum-processed- despread signals thereby generating a subtracted signal. The channel- correlator despreads the subtracted signal.
