| Abstract: | Communication System of Speech Secure with Chaos is researched and it is based on Software Radio in this paper. Used the Logistic Map for discrete value time serial and the Rossler's equation for time continuity to produce chaotic state and modulate in to the software radio to form a set of the Communication System of Speech Secure with Chaos. Experimentalized emulate of speech secure communication and their system by the computer. Two kind of chaotic signal and their produce principle were discussed in this paper, and its security speciality were compared and analyzed in the software radio system. |
