Abstract
A method of operation of a receiver of a mobile station or a base station of a radio access network and corresponding equipment, the method for especial use in providing interference cancellation according to a single antenna interference cancellation (SAIC) algorithm. The method includes a step () in which a channel estimator () estimates channel impulse response components for use by a SAIC equalizer (); in estimating the channel impulse response components, the channel estimator () minimizes a special cost function (J(h)) with respect to the components of the channel impulse response h. In some embodiments, the method uses an iterative least mean squares procedure to minimize the cost function (J(h)).
