Simulations are conducted to investigate the Bit Error Rate (BER) performance of OFDM system as a function of energy per bit to noise power spectral density ratio E_b/N_0 for both cases of conventional OFDM (FFT-OFDM) and proposed OFDM in this paper based on DFrFT (Fr-OFDM). Simulations...
Moreover, the discrete fractional Fourier transform (DFrFT) is used to improve the communication system's performance over the OFDM. The proposed low-complexity equaliser could improve the OFDM, and the DFrFT-orthogonal chirp-division multiplexing (DFrFT-OCDM) system's performance, as illustrated in...
To verify the design of the DFrFT-based OFDM system, we use FPGA-in-the-Loop (FIL) co-simulation method to evaluate bit error rate (BER) in presence of carrier frequency offset (CFO) when transmission takes place over a frequency selective Rayleigh fading channel....
