Wireless Chaos-Based Communication Systems: A Comprehensive Survey

Abstract

Since the early 1990s, a large number of chaos-based communication systems have been proposed exploiting the properties of chaotic waveforms. The motivation lies in the significant advantages provided by this class of non-linear signals. For this aim, many communication schemes and applications have been specially designed for chaos-based communication systems where energy, data rate, and synchronization awareness are considered in most designs. Recently, the major focus, however, has been given to the non-coherent chaos-based systems to benefit from the advantages of chaotic signals and noncoherent detection and to avoid the use of chaotic synchronization, which suffers from weak performance in the presence of additive noise. This paper presents a comprehensive survey of the entire wireless radio frequency chaos-based communication systems. First, it outlines the challenges of chaos implementations and synchronization methods, followed by comprehensive literature review and analysis of chaos-based coherent techniques and their applications. In the second part of the survey, we offer a taxonomy of the current literature by focusing on non-coherent detection methods. For each modulation class, this paper categorizes different transmission techniques by elaborating on its modulation, receiver type, data rate, complexity, energy efficiency, multiple access scheme, and performance. In addition, this survey reports on the analysis of tradeoff between different chaos-based communication systems. Finally, several concluding remarks are discussed.

Digital Communication System with High Security and High Noise Immunity: Security Analysis and Simulation

“…In a CDMA scheme, each user is assigned a particular spreading sequence to map the information signal. Thus, the spreading information signal using a particular sequence increases the bandwidth of the information signal by a factor of N, which is known as the spreading factor or processing gain [1].…”

“…The proposed cryptosystem for the CDMA system is compared to a one-time pad. One-time pad encryption is an unbreakable encryption method [1][2][3]. The encryption method of the one-time pad involves one truly random bit (Letter pad) corresponding to one bit of the plaintext by using the bitwise Exclusive OR gate (XOR) to produce one bit [1].…”

The key and plaintext must be equal length, the key must satisfy a randomness test and the key must only be used once.…”
