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 …

A joint energy and correlation detection aided orthogonal frequency division multiplexing
differential chaos shift keying (JECD-OFDM-DCSK) system is presented in this paper, where …

A multiband OFDM transmitter and receiver are presented for underwater communications at
low SNR. Compared with a single-band OFDM scheme, the multiband approach leads to a …

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 …

In this paper, we present a study of the bit error rate (BER) performance of chaos-based DS-
CDMA system over an m-distributed fading channel. In this system, the perfect …

Underwater acoustic (UWA) communications face many challenges, such as large multipath
delay, severe fading and the time-varying distortions. Chaotic modulations have shown …

An accurate approach to compute the bit error rate expression for multiuser chaosbased DS-
CDMA system is presented in this paper. For more realistic communication system a slow …

The chaotic direct sequence spread spectrum (CD3S) has been extensively studied and
accepted as an approach of chaotic secure communication. However, we find that CD3S is …

提出了一种新型的混沌保密通信破译方法, 并破译了混沌直接序列扩频保密通信(简称混沌直扩).
针对混沌直扩信号中只有一个混沌吸引子的特点, 基于混沌系统广义同步的思想 …

Due to the inherent noise-like characteristic of chaotic signals and their sensitivity to the
initial value, chaotic direct sequence spread spectrum (CD3S) signals have the advantages …
