“…Over the past few decades, most researches have been concentrating on these properties and have made an effort to address the different topics related to chaosbased communications [3]. For instance, the studies performed explored spread-spectrum communication systems, their modulation schemes, chaos-based coding, as well as multiple-access schemes [4]. Chaos-based communication systems are divided into two classes, as they are based on coherent and non-coherent detection [5].…”

This paper proposes an improved chaos-based M-ary modulation system. It reproduces deterministic chaotic dynamics to create M-ary non-coherent modulation. The proposed modulation system transmits data using autonomous chaotic sequences. It separates the chaotic dynamics through the use of interleavers and realigns them through the use deinterleavers. The simulation results show that the improved scheme overperforms its traditional counterpart. The degree of improvement grows as the M-ary order is increased, with a penalty of increased system complexity.

“…Can the proposed system provides high security to the voice signal? To realize this, a number of voice encryption techniques have been studded [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. From these researches, the chaotic system was regarded as an efficient technique for voice data.…”

With the significant development in communication systems especially in the public channels through which our information travels, there are more increasing in the channels problems. The information security is the important one that should be enhanced. This paper presents a chaos-based speech scrambling system. Chaotic maps have been successfully used for large-scale data encryption such as image, audio and video data, due to their good properties such as pseudo-randomness, sensitivity to changes in initial conditions and system parameters and a periodicity. In this paper a security model based on chaotic system has been designed to be used to encrypt voice signal, chaotic duffing map used for digital Scrambling, each samples of the speech are divided into 8 bits. The simulation results show that the Cpestral Distance Measure (CD) in the proposed system is increased by (4.559) by comparing with the time domain scrambling which is about four times that gives from the analog scrambling. In addition, d<sub>lpc</sub> increased to (4.428) as comparing with time domain. The key space in this proposed is 11.8336*10<sup>64</sup>×range of parameters.
