A signal generating unit (100) is provided for generating signals. The signal generating unit comprises an IFFT unit (101) for generating an output signal; a filter unit (102) operatively connected to the IFFT unit; and a subtractor (103) operatively connected to the IFFT unit and to the filter unit, said subtractor being adapted to subtract the interference from the output signal. A signal receiving unit (200, 300) is provided for receiving signals. The signal generating unit comprises a filter unit (202, 302); a subtractor (203, 303) operatively connected to the filter unit; and an FFT unit (201, 301) operatively connected to the subtractor. Methods for receiving and generating signals are also provided. |
