Abstract
A multi-path interference canceller cancels interference in a signal received by a receiver in a wideband CDMA communications system. A first stage of the canceller has as input the received signal. Each next stage has as input a delayed version of the input of the previous stage. Each stage includes a first channel estimation and interference generation unit for estimating interference in high-speed signal components of the input signal, and a second channel estimation and interference generation unit for estimating interference in low-speed signal components of the input signal. The interference estimated in the previous stage by the first and second channel estimation and interference generation units is then removed from the input signal of the next stage.
