A Novel Frequency-modulated Differential Chaos Shift Keying Modulation Scheme Based on Phase Separation∗
In frequency-modulated differential chaos shift keying (FM-DCSK), the separation of the chaotic reference and information-bearing wavelets is performed in time domain. This separation method not only limits the attainable data rate but also demands delay components in transceiver circuits. Due to the fact that wideband radio frequency (RF) delay lines are extremely difficult to implement with C...
متن کاملDesign of the differential chaos shift keying communication system based on DSP builder
Chaotic communication has the good secrecy. It is an important branch of the modern secure communication. Differential chaos shift keying (DCSK) communication system adopts shift keying to separate the reference signal and data signal. It has a strong resistance to the multipath channel. For FPGA systems design shortcomings using a hardware description language directly, the DCSK communication ...
متن کاملDesign and Analysis of an OFDM-based Differential Chaos Shift Keying Communication System
—In this paper, a new non-coherent chaos-based communication scheme, named orthogonal frequency division multiplexing based different chaos shift keying (OFDM-DCSK), is presented inspired by multi-carrier direct sequence codedivision multiple access (MC-DS-CDMA) system, multi-carrier DCSK (MC-DCSK) system, and channel estimation of OFDM system. In this scheme, all of the occupied subcarriers a...
متن کاملON/OFF Phase Shift Keying for Chaos-Encrypted Communication Using External-Cavity Semiconductor Lasers
Synchronization phenomena of two chaotically emitting semiconductor lasers subject to delayed optical feedback are investigated. The lasers are unidirectionally coupled via their optical fields. Our experimental and numerical studies demonstrate that the relative optical feedback phase is of decisive importance: a characteristic synchronization scenario evolves under variation of the relative o...
