A multiple access technique for differential chaos shift keying
Various chaos-based digital communications techniques have been proposed recently. Among them, differential chaos shift keying (DCSK) allows the receiving end to decode the signal using noncoherent detection. This paper proposes and analyses a multiple access scheme for DCSK. A simple 1-dimensional iterative map has been used to generate the chaotic signals for all users. Bit error probabilitie...
متن کاملApplications of Symbolic Dynamics to Differential Chaos Shift Keying
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 s...
متن کاملMultilevel code-shifted differential-chaos-shift-keying system
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...
متن کاملSecurity of Power Packet Dispatching Using Differential Chaos Shift Keying
This paper investigates and confirms one advantageous function of a power packet dispatching system, which has been proposed by authors’ group with being apart from the conventional power distribution system. Here is focused on the function to establish the security of power packet dispatching for prohibiting not only information but also power of power packet from being stolen by attackers. Fo...
متن کاملPerformance of Differential Chaos Shift Keying over Multipath Fading Channels
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
