Abstract
A method is disclosed of a wireless receiver configured for spatial selective reception. The method is for mitigation of an interfering signal leaked into a frequency range of a desired signal due to non-linearity of hardware components of the receiver. The method comprises receiving a composite signal comprising the desired signal and the interfering signal, filtering the composite signal using a spatial filter for a channel response of the desired signal to provide a first intermediate signal component, and filtering the composite signal using a spatial filter for a channel response of the interfering signal to provide a second intermediate signal component. The method also comprises estimating a squared amplitude of the interfering signal based on the second intermediate signal component and a model of the non-linearity, and estimating the desired signal based on the first intermediate signal component, the estimated squared amplitude of the interfering signal, and the model of the non-linearity. Corresponding apparatus, wireless receiver, wireless communication device and computer program product are also disclosed.
