Abstract

Based on the explicit relationship between the fractional Fourier transform properties of chirp signals and their parameters (chirp-rate and central-frequency), a novel modulation named multiple chirp-rate shift keying (MCrSK) which could be demodulated with a method based on fractional Fourier transform was proposed. This modulation holds a constant envelope and provides a better BER performance than MPSK. Further, MCrSK can be used with MFSK, which gives a trade-off between BER and bandwidth efficiency by modulation parameters adjusting.
