Abstract :
The authors propose a group demodulator that employs the multisymbol chirp Fourier transform to demodulate pulse-shaped and time-asynchronous signals. Computer simulation results show that the bit error rate degradation of the proposed group demodulator at BER=10-3 is less than 0.3 dB with a 7 symbol chirp Fourier transform
