Method and apparatus for interference cancellation in a communication system

In a communication system, an apparatus comprising:

• a radio frequency receiver for converting an encoded and spectrum spread received signal to received samples;
• a searcher in combination with a finger element for determining a channel estimate based on a set of pilot signal samples, wherein said set of pilot signal samples are included in said received samples;
• a decoder for decoding said received samples in accordance with said channel estimate to produce decoded received samples;
• a controller for re-encoding and re-spreading said decoded received samples to produce re-encoded and re-spread samples, and for modifying said re-encoded and re-spread samples based on said channel estimate to produce channel modified re-encoded and re-spread samples, wherein said controller performs said modifying by multiplying said re-encoded and re-spread samples by said first channel estimate to produce said channel modified re-encoded and re-spread samples.
