Abstract:
In this paper, we investigate Chaos-based communication systems in the context of secure image transmission. The proposed model combined the secure image transmission process with non-coherent chaos communication system over multipath fading channel. Security of image signal is required to be transmitted reliably through a communication channel or when information is managed by computing units. Security issues are becoming problematic in multimedia applications and network systems. Thus, providing a secure transmission of data is an important theme tackled by researchers. The pace at which data is sent is an important consideration. Wireless communications are dominated by coherent communications at this time. To decode received data, such systems need exact knowledge of the receiver's channel condition. In chaotic communication systems, noncoherent detection, which doesn't need a lot of complicated the synchronization of the transmitter and receiver, perhaps an interesting alternative. The proposed system is evaluated through measures such as complexity, data throughput, and security. In order to take use of chaotic signals and noncoherent detection while avoiding chaotic synchronization, which performs poorly in the presence of additive noise, non-coherent chaos systems have attracted a lot of attention. The results presented in this research disclose new ideas related to the design of a new non-coherent differential chaos shift keying communication system.
