Generalized frequency division multiplexing (GFDM) is considered as a candidate waveform for 5G wireless communication systems. It is the generalize form of the orthogonal frequency division multiplexing (OFDM) that includes a number of subcarriers and subsymbols. An alternative waveform referred as the superimposed waveform in this study, was recently proposed to increase the data rate. The superimposed waveform is based on using orthogonal polynomial in each grid of time-frequency lattice… Expand
