Abstract :
A multiple-access technique for use with differential chaos shift keying is proposed and analyzed in this paper. A simple one-dimensional iterative map 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 numbers of users and computer simulations are performed to verify the results
