“…Due to excessive pilot broadcasts on slow-fading channels, the transmitter will repeatedly send pilot symbols, squandering resources. Coherent communication suffers greatly from channel estimate errors, and this deterioration is exacerbated under conditions of high mobility [18], [19], [20], [21], [22], [23].…”

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.

Halangan pada Line of Sight (LOS) dapat menyebabkan difraksi (pembelokan), refleksi (pemantulan), dan scattering (penghamburan) pada sinyal informasi dimana akan mengurangi kualitas sinyal informasi yang diterima pada sisi penerima. Hal tersebut mengakibatkan adanya sifat konstruktif maupun destruktif pada sinyal di sisi penerima. Contoh sifat destruktif yang sering terjadi yakni fading dan delay. Sistem penerima correlation receiver diimplementasikan guna mengatasi masalah yang timbul akibat efek dari multipath fading. Untuk memperoleh sinyal dengan nilai error minimum, maka diperlukan analisis terkait proses transmisi pada masingmasing komponen multipath. Hasil analisis diperoleh bahwa unjuk kerja dari Kode PN (Pseudo Noise) pada kanal frequency selective fading yang lebih baik adalah variasi komponen multipath = 3 dibandingkan dengan variasi komponen multipath = 6 dan yang paling buruk adalah variasi komponen multipath = 7. Hal ini dibuktikan dengan melihat nilai Bit Error Rate (BER) saat Energy Per Bit To Noise Power Spectral Density Ratio (Eb/No) = 10 dengan komponen multipath = 3 memiliki nilai BER 0,00368, sedangkan komponen multipath = 6 dan komponen multipath = 7 memiliki nilai BER berturutturut adalah 0,00386 dan 0,00507. Berdasarkan hasil analisis tersebut dapat diambil simpulan bahwa jumlah komponen multipath yang ada berpengaruh terhadap kualitas sinyal yang diterima.

Time hopping spread spectrum (THSS) system and chaotic system have been studied as candidates of the anti-jamming (AJ) systems with substantial advantages. However, THSS systems suffer from the strict synchronization prerequisite. In order to overcome the shortcomings of the THSS system and utilize the profits of the non-coherent chaotic system, we first propose a novel TH-NRDCSK system to enhance the bit error rate (BER) performance of the conventional non-coherent THSS system and relieve the strict synchronization issue of coherent THSS systems. Then, we analyze the performance of the proposed system under additive white Gaussian noise (AWGN) channel and jamming environment. Finally, we implement the simulation to demonstrate the consistency of the analysis and the simulation results and to disclose the effects of the system parameters on system's AJ performance. Moreover, the performance of the proposed system is compared to that of conventional counterparts to look at the benefits of integrating chaotic and THSS systems. The simulation results show that the proposed system significantly outperforms conventional counterparts in a practical environment.
