Abstract:
A method for compensating for an interfering signal included in an input signal (rk+1) carrying a digital payload signal to obtain an interference-compensated signal (zk+1), comprising the steps of:producing an interference estimate (Ãªk+1) for an interfering signal sample value; predicting from said interference estimate (Ãªk+1) a next sample value for the interfering signal; subtracting said interference estimate (Ãªk+1) from a signal sample (yk+1) of an uncompensated signal derived from said input signal (rk+1); making a decision (sk+1) on a sample value of the interference-compensated signal (zk+1); wherein said producing step includes a step of adaptively forming said interference estimate (Ãªk+1) as a function of at least one previous decision value (sk) of said decision and at least one previous signal sample (yk) of said uncompensated signal.
