Zusammenfassung:	Hyperbolic fractional Fourier transform (HFRFT) based on hyperbolic chirps utilisation in FRFT is introduced. The exact BER of the HFRFT in a Rician fading channel is derived mathematically. In high speed vehicle applications, specially in LEO orbit satellite communications that have an inherent high Doppler frequency shift, with the HFRFT-OFDM system better BERs than other OFDM systems can be achieved.
