Performance evaluation of a multiple access DCSK system under a noisy multiuser environment [articol]

Abstract

In this paper a multiple-access technique for use with DCSK (MA-DCSK) under a noisy condition is proposed and analyzed. In order to evaluate the performance of the system, a simple one dimensional iterative map is used to generate the chaotic signals for all users. As would be expected, the proposed scheme achieves similar error probabilities for all users and the error performance degrades as the number of users increases. Bit-error rates for different number of users and computer simulations are performed to verify the results.
