What is it about?
This paper considers a novel type of signal for 5G communications based on FBMC-QAM. In this new method, the innovative type of fractional Fourier transform on the basis of hyperbolic chirps that denominated as hyperbolic FRFT, is implemented. The closed-form of bit error probability of the introduced signal in Rayleigh and Rician selective fading channels, is derived. According to simulations results, utilization of the HFRFT-FBMC system can attain the better bit error probability in noisy channels, especially in the scenarios of high Doppler frequency rates.

Why is it important?
The fifth generation (5G) communication systems is a novel and attractive concept of new wireless networks, which has fascinated vast range of researches. The main purpose of 5G systems is to enable ubiquitous connections for anything. The intended aim needs to utilize robust physical layer structures that can cope with several types of interference, which the introduced innovative signal can be what we want.
Perspectives
New generation of wireless communication needs to have robust physical layer to support multi user in hard situation of communications like high speed movement. In this paper, we prove that signals based on fractional Fourier and hyperbolic fractional Fourier transform can overcome the challenges we will face it in future communication systems.
