Abstract (en)
[origin: EP1924044A1] The apparatus (400) has a limiter for producing a limited signal (S) from a signal having a set of subcarriers. A coefficient ascertainment unit (404) determines coefficients (Ck) for unused subcarriers of the signal from the limited signal. A signal generator (406) generates a reduction signal (Xn) from the coefficients, where the reduction signal is combined with the signal to form a reduced signal. The coefficient ascertainment unit projects the limited signal onto a base formula. An independent claim is also included for a method for producing a reduction signal.
