Abstract
Generalized frequency division multiplexing (GFDM) is an upcoming modulation method for fifth generation (5G) wireless communication systems with many advantages over conventional orthogonal frequency division multiplexing (OFDM). In this work, GFDM with clipping and filtering technique is proposed and its performance in terms of peak to average power ratio (PAPR) is presented. The proposed GFDM system along with Rapp’s solid state high power amplifier (SSPA) is simulated to evaluate its PAPR and BER performance. The performance of the present system is compared with the OFDM system for equal and unequal spectral efficiency conditions. The simulation results show that at equal spectral efficiency condition (ESE), the PAPR of clipped and filtered GFDM signal is reduced by 1.6 dB as compared to clipped and filtered OFDM signal with almost similar BER performance. In addition to that, the complexity of GFDM system is less than that of OFDM for equal spectral efficiency condition.
