Abstract
According to an aspect, there is provided a waveform processing device. The waveform processing device includes circuitry for receiving an input signal including one or more subsequent orthogonal frequency division multiplexing, OFDM, symbol blocks each of which includes a cyclic prefix and an OFDM data block and corresponds to one or more subbands. Further, the waveform processing device includes circuitry for segmenting each OFDM symbol block of the input signal into a set of a pre-defined number of partially overlapping signal blocks of equal length so that non-overlapping samples of the pre-defined number of partially overlapping signal blocks in each set include, in combination, an OFDM data block. Moreover, the waveform processing device includes circuitry for filtering each signal block in each set and for combining the filtered signal blocks in each set using overlap-and-save processing to produce one or more filtered OFDM data blocks for each subband.
