英文摘要	Conference Name:OCEANS 2014 - Taipei. Conference Address: Taipei, Taiwan. Time:April 7, 2014 - April 10, 2014.; Multiuser underwater acoustic communication is one of the enabling technologies for the autonomous oceans sampling network (AOSN). Based on explicit relationship between fractional Fourier transform properties of chirp signal and its parameters, we proposed a new modulation and demodulation scheme named multicarrier-multiple chirp rate shift keying (MC-MCrSK). The scheme can support four users communication via underwater acoustic channel with 10 KHz bandwidth. Receiver can increase robustness by virtual time reversal mirror technology (VTRM). The validity of the simulation comparison is verified in experiment. 425 bps data rate per user of the proposed communication scheme is realized in 10 KHz bandwidth.
