Abstract  Abstract

The present invention provides a method for receiving a traffic signal in a code division multiple access communication system the system transmitting a traffic signal over a shared spectrum traffic signal having an associated code the method comprising:
* receiving signals over the shared spectrum;
* sampling the received signals to produce samples;
* delaying the samples to produce a window the window having evenly time spaced samples;
* despreading the samples and determining a weight for each despread window sample using an adaptive algorithm the adaptive algorithm providing a determination of an optimum weight for each of a plurality of despread components; and
* adaptively filtering the received signals using the associated code of the traffic signal and the determined weights to produce data of the traffic signal.
