Acoustic communication is a key technology to exchange information underwater, which is of great significance to explore marine resources and to marine defense. The underwater acoustic channel is a time-space-frequency varying channel characterized by serious multipath effect, limited frequency band, complex environmental noises and significant doppler frequency shift phenomenon, which makes underwater acoustic communication with low Bit Error Rate (BER) to be a challenging task. A novel chaotic spread spectrum acoustic communication method with low BER is proposed in this paper. A chaotic signal, generated by a

“…Reliable electronic hardware implementations of chaotic sequence generators based on recursion of maps by linear analogue functions are currently impossible owing to the manufacturing difficulties [78]. Fortunately, several modified and alternative approaches based on digital nonlinear functions were proposed and proved to have satisfying performances [79]. Despite this, recent studies have proved that chaotic sequences can be observed and recovered by blind detection methods based on the estimation of symbol periods [80].…”

Unmanned combat aerial vehicles (UCAVs) that swarm with both autonomous decision-making and cooperative attacking have been regarded as revolutionary elements of modern warfare. In such a swarm, inter-group connectivity must be ensured in a network to maintain a collective consensus. In recent years, academia and industry have made many efforts to achieve common tactical data link systems and commercial drone networks. However, the existing results have difficulty meeting the needs of cooperative autonomous UCAV swarms with both hypersonic mobility and time sensitivity in severe confrontation scenarios. In this article, we conduct an in-depth investigation of the network used for the hypersonic UCAV swarms, which can be considered as a special form of mobile wireless network. Furthermore, faced with specific functional demands, we summarize the main challenges of designing this dedicated network. In addition, a comprehensive survey of potential solutions for the network design is presented. Lastly, we discuss the possible capabilities of the network given the current forefront of technology, as well as remaining challenges and open issues.

“…Other than these, more advanced and novel techniques relevant to spread spectrum digital communication system design and optimization are proposed in recent years. In [34], an implementation scheme of a typical spread spectrum digital communication system using field programmable gate array (FPGA) and Pseudo-Chaotic Sequences (PCS) are outlined; correlation delay shift keying is combined with conventional spread spectrum technique in [35]. Also, high-bit rate Barker code, Hybrid Spread-Spectrum (HSS) system and optimal jamming strategies are preliminarily analyzed in recent years, which are worth further investigating [36]- [38].…”

In this paper, we will review spread spectrum signaling techniques in terms of performance, applications and implementation. Specifically, we focus on direct sequence spread spectrum signaling and CDMA, as the most important applications of spread spectrum signaling techniques, analyzing them in details. With a number of theoretical derivations and simulations, their mathematical characteristics, merits and drawbacks can be revealed. By reading this paper, the readers are expected to have a broad understanding of spread spectrum signaling as well as of direct sequence spread spectrum signaling and CDMA.
