  • Abstract
    In this paper, a modified multiple-access scheme is proposed and analyzed on the base of the time-delay-based multiple-access technique using differential chaos shift keying (DCSK). Zero-mean Logistic chaos map with different initial values is used to generate the chaotic signals for all users and the average data rates for the users are identical. Bit error rates are derived numerically for different number of users, spreading factor, and the bit-energy-to -noise-power-spectral-density ratio under AGWN channel model or multipath Rayleigh fading channel model. Finally, computer simulations are performed to verify the results.
