Abstract

An apparatus and a method for orthogonal frequency-division multiplexing (OFDM), wherein a first OFDM symbol (202) comprises a first part at a beginning of the first OFDM symbol (202) and a last part at an end of the first OFDM symbol (202), wherein a second OFDM symbol (204) comprises a first part at a beginning of the second OFDM symbol (204) and a last part at an end of the second OFDM symbol (204), wherein the method comprises choosing samples from the last part of the first OFDM symbol (202) and the first part of the second OFDM symbol (204), converting the samples (202, 204) into frequency-domain samples, multiplying the frequency-domain samples by a frequency-domain window to determine windowed samples in the frequency domain, converting the windowed samples in the frequency domain into time-domain samples in the time domain, multiplying the time-domain samples with a time-domain window (400) to determine samples for a boundary, multiplying the time-domain samples with a complementary window (402) of the time-domain window (400) to determine complementary-windowed time-domain samples, determining a result of overlapping the complementary-windowed time domain-samples and the samples and adding the complementary-windowed time-domain samples and the samples in the boundary.
