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.
