Abstract: A spread-spectrum noise canceller (390) is provided for cancelling user code noise from a spread-spectrum communication channel. The spread-spectrum noise canceller (390) includes a receiver for receiving a spread-spectrum signal (302) including a first and at least a second signal as well as a noise canceller (390) operatively coupled to the receiver for reducing spread-spectrum noise in the first received signal by substantially processing the at least second received signal out of the received spread-spectrum signal (302). In addition, a method is provided which cancels user code noise from a spread-spectrum communication channel. The method includes receiving a spread-spectrum signal (302) including a first and at least a second signal and subsequently reducing spread-spectrum noise in the first received signal by substantially processing the at least second received signal out of the received spread-spectrum signal (302).
