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.

Method of interference cancellation in a CDMA wireless communication system, characterized by the fact that it 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.
Interference cancellation device for a CDMA wireless communication system, characterized by the fact that it comprises reception means for receiving an incident digital signal containing a user signal transmitted on a CDMA user physical channel and an interfering signal, preprocessing means for projecting said incident digital signal onto a projection space orthogonal to the space containing said interfering signal, and a flake receiver connected to the output of the preprocessing means, and matched to the CDMA user physical channel for detecting the data contained in said user signal.
