Abstract: Embodiments relate to a receiver (310) for receiving a multicarrier signal. The multicarrier signal comprises a first frequency block with a first group of subcarriers, the first frequency block being filtered with a first frequency block specific sideband suppression filter (106-1) for sideband suppression outside of said first frequency block, and at least a second frequency block with at least a second group of subcarriers, the second frequency block being filtered with a second frequency block specific sideband suppression filter (106-2) for sideband suppression outside of said second frequency block. The receiver (310) comprises a filter module (320) operable to perform an inverse sideband suppression filter operation for the first and at least the second frequency block. The Application proposes a new so-called Universal Filtered Multi-Carrier or UFMC system which can be interpreted as a generalization of FBMC and filtered OFDM. While FBMC filters each subcarrier and the latter filters the entire band, UFMC filters blocks of multiple subcarriers. The frequency-block-wise filtering of UFMC brings in additional flexibility: the block bandpass filters are spectrally broader than FBMC and thus shorter in time.
