Abstract: 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-processi ng circuits, subtracting circuits, and channel correlators. Using a plurality o f 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.

Abstract: The canceller includes correlators (54,64,74), spread spectrum processors (55,65,75), subtracting circuits (150) and channel correlators (146). Using chip-code signals generated from chip codeword signal generators (52,62,72), the correlators (54,64,74) despread the spread spectrum signal. The spread spectrum processors (55,65,75) use a timed version of the chip-code signals generated for spread spectrum processing the despread signals. The subtracting circuits (150) subtract from the spread spectrum signal, each of the N-1 spread spectrum despread signals generating a subtracted signal for recovering a code channel using an ith chip-code signal. The channel-correlator (146) despreads the subtracted signal.
