ABSTRACT:
A method and apparatus are provided including setting an interference level threshold, to sample the received signal, storing the sample values as first sample value vectors of a predetermined length, and forming prediction matrices of the first sample value vectors. The method and apparatus also modify prediction matrices in such a way that the interference components and the components of the desired signal are separated from each other, form signal matrices by performing rank reduction for each prediction matrix by rejecting those sample values or elements representing them that exceed the interference level threshold, form second sample value vectors of the signal matrices, and sum up sample values of second sample value vectors time-coherently to average the noise by sliding the sample value window, to be used to attenuate interference in the system.
