Abstract
The method of interference cancellation in a CDMA wireless communication system comprises receiving an incident digital signal containing a user signal transmitted on a CDMA user physical channel and an interfering signal, projecting said incident digital signal onto a projection space orthogonal to the space containing said interfering signal, filtering said projected signal with a filter matched to the CDMA user physical channel for detecting the data contained in said user signal.
