PROJECT TITLE :
Discrete Fourier transform spreading-based generalised frequency division multiplexing
Generalised frequency division multiplexing (GFDM) has gained important importance as a contender for the fifth generation (5G) air interface. The peak-to-average power ratio (PAPR) of GFDM is high because of the employment of a same pulse shaping filter per subcarrier and also the addition of various subcarriers at the transmitter. Proposed is the use of discrete Fourier remodel (DFT) spreading-based GFDM transmission to reduce the PAPR. It's found that DFT spreading helps to scale back the PAPR of GFDM considerably. It's also seen that the bit error rate performance, which is computed through simulation and using an analytical expression of the signal-to-interference-and noise ratio, is not compromised by DFT spreading but rather is improved in the frequency selective fading channel.
