| Abstract | Generalised frequency division multiplexing (GFDM) has gained significant importance as a contender for the fifth generation (5G) air interface. The peak-to-average power ratio (PAPR) of GFDM is high due to the use of a same pulse shaping filter per subcarrier and the addition of different subcarriers at the transmitter. Proposed is the use of discrete Fourier transform (DFT) spreading-based GFDM transmission to reduce the PAPR. It is found that DFT spreading helps to reduce the PAPR of GFDM significantly. It is also seen that the bit error rate performance, which is computed through simulation and using an analytical expression of the signal-to-interference-plus noise ratio, is not compromised by DFT spreading but rather is improved in the frequency selective fading channel. |
