摘要: In this paper, we propose a new asynchronous multiuser communication system based on spread spectrum and chaotic symbolic dynamics modulation. By combining modulation, the proposed provides increased security by reducing probability of detection while allowing transmissions. The sequence synchronization chaos is studied. A time acquisition technique serial search to achieve synchronization. An analysis carried out determine detection, false alarm bit error rate system. Simulation results show that can under low signal-to-noise ratios, also confirm our analytically computed expressions.
