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, has been very interesting to many people. Many systems that don’t make sense are being shown in this section, this covers measures like as complexity, data throughput, and security. Non-coherent chaos has received a lot of attention in order to leverage chaotic signals and noncoherent detection while avoiding chaotic synchronization, which has poor performance in the presence of additive noise. This offers the reader an idea of what is being done currently and what research is still required in the future.
