Applications of Symbolic Dynamics to Differential Chaos Shift Keying
نویسنده
چکیده
In this paper we propose an enhanced version of the DCSK (Differential Chaos Shift Keying) scheme where the carrier symbolic dynamics are exploited for conveying useful information. This is achieved by means of a pseudo-chaotic encoder which spreads the input sequence approximating the dynamics of the Bernoulli shift. The information encoded in the pseudo-chaotic carrier is retrieved by using standard maximum-likelihood detection. It is shown that the proposed method can also be useful for noise filtering purposes.

Maximum Likelihood Detection of Symbolic Dynamics in Communication Systems with Chaos Shift Keying
Abstract— The paper describes the application of the Viterbi algorithm in the implmentation of a maximum likelihood receiver in a chaos communication scheme. The Viterbi decoder is constructed based on a symbolic state representation of the transmitter’s chaos generator. The presented simulation results show that the classical Binary Phase Shift Keying (BPSK) modulation scheme can be slightly o...
متن کاملCo-existence of chaos-based and conventional digital communication systems
This paper studies the performance of selected chaos-based communication systems whose spectrum overlaps with that of conventional narrowband systems. Such a scenario may occur in normal practice when chaos-based systems are introduced while the conventional systems are still in operation. The particular chaos-based systems under study are the coherent chaos-shift-keying (CSK) system and the no...

The M -ary differential-chaos-shift-keying (M -ary DCSK) system offers a good noise performance over an additive white Gaussian noise (AWGN) channel in the category of non-coherent detection chaotic systems. However, the way that the M -ary DCSK system utilizes the available Walsh codes results in a relatively low bandwidth efficiency. Moreover, the number of delay elements required at the tran...

We analyze the performance of Differential Chaos Shift Keying (DCSK) over communication channels exhibiting multipath fading. Formulas are derived for the bit error rate (BER) performance in the single user case and compared with simulation results. Keywords—chaos, communication, fading, DCSK
متن کاملLorenz-based Chaotic Secure Communication Schemes
Secure communication systems employing chaos have recently attracted significant interest. This is partly due to their high unpredictability and simplicity of implementation over conventional secure communications systems. This study presents the implementation of four chaotic modulation techniques employing Lorenz system as chaos generator. The techniques are Chaotic Masking (CM), Chaos Shift ...
