Methods and system removing co-channel interference from a digital signal. In this method, the digital signal interfered by an interference signal is received, wherein the interference signal comprises consecutive sections, each of which contains N symbols. An average signal is generated by calculating an average over the received digital signal at periodic time instants (n-k*N), wherein N is a constant, n denotes the present time instant and k is a non-negative integer. A first estimated interference signal is generated by filtering the average signal, and the first estimated interference signal is subtracted from the received digital signal and output a first signal.
