FRAT-OFDM vs. FFT-OFDM Systems in Fading AWGN Channels

Digital wireless communication design for high speed data for orthogonal frequency division multiplexing system has been investigated. Fast Fourier transform and finite Radon transform were applied for the investigation. Block diagrams systems with fast Fourier transform and finite Radon transform has been presented. Simulation and comparison (normalized and non-normalized) of fast Fourier transform and finite Radon transform efficiency in orthogonal frequency division multiplexing system was carried out through MATLAB program. The application of finite Radon transform has been shown to provide the gain in the parameter signal to noise ratio from 2 dB to 15 dB.References 5, figures 8, tables 2.
