1. A method for recovering data transmitted over a plurality of channels in a wireless code division multiple access communication system, the method comprising:receiving the plurality of channels as a received signal, each channel associated with a code; subtracting for each of the plurality of channels others of the plurality of channels from the received signal and despreading a result of that subtracting as data for that channel; wherein the subtracting others of the plurality of channels including for each channel; despreading the received signal with the others channels codes; respreading the despread others channel codes using the other channels codes; and subtracting from the received signal the respread other channels. 2. The method of claim 1 wherein the despreading is performed by a mixer.3. The method of claim 1 wherein the despreading is performed by a matched filter.4. A receiver for recovering data transmitted over a plurality of channels in a wireless code division multiple access communication system, the receiver comprising:means for receiving the plurality of channels as a received signal, each channel associated with a code; means for subtracting for each of the plurality of channels, others of the plurality of channels from the received signal and despreading a result of that subtracting as data for that channel; wherein the means for subtracting includes for each channel; means for despreading the received signal with the others channels codes; means for respreading the despread others channels codes; and means for subtracting from the received signal the respread other channels. 5. The receiver of claim 4 wherein the despreading means is a mixer.6. The receiver of claim 4 wherein the despreading means is a matched filter.7. A receiver for recovering data transmitted over a plurality of channels in a wireless code division multiple access communication system, the receiver comprising:an input configured to receive the plurality of channels as a received signal, each channel associated with a code; and for each of the plurality of channels, a subtractor for subtracting others of the plurality of channels from the received signal and despreading a result of that subtracting as data for that channel; for each channel, a first mixer operatively coupled to the input for despreading the received signal with that channel code; for each channel, a second mixer for respreading that channel despread signal; and wherein for each channel, the subtracter subtracts from the received signal the respread channels other than that channel. 8. A receiver for recovering data transmitted over a plurality of channels in a wireless code division multiple access communication system, the receiver comprising:an input configured to receive the plurality of channels as a received signal, each channel associated with a code; and for each of the plurality of channels, a subtractor for subtracting others of the plurality of channels from the received signal and despreading a result of that subtracting as data for that channel; for each channel, a matched filter operatively coupled to the input for despreading the received signal with that channel code; for each channel, a mixer for respreading that channel despread signal; and wherein for each channel, the subtractor subtracts from the received signal the respread channels other than that channel.
