A Generalized BER Prediction Method for Differential Chaos Shift Keying System Through Different Communication Channels

In this paper, we present a generalized accurate methodology to predict the bit error rate performance for non-coherent chaos-based communication systems. The Gaussian approximation approach, which is widely used to compute the performance of such systems, leads to inaccurate results, especially with respect to low spreading factors. Our new approach based on the chaos bit energy distribution g...

Performance 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

Analysis of Network Coding Schemes for Differential Chaos Shift Keying Communication System

In this paper we design network coding schemes for Differential Chaos Shift Keying (DCSK) modulation. In this work, non-coherent chaos-based communication system is used due to its simplicity and robustness to multipath propagation effects, while dispensing with any channel state information knowledge at the receiver. We propose a relay network using network coding and DCSK, where we first pres...

Multilevel 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...

Comparison of different Chaos shift keying methods

This paper examines a number of chaos shift keying methods. Different approaches for the optimization of the transmitter and the receiver (based on statistical arguments) are compared through simulation. Based on the results, the tradeoff between computational complexity and performance is discussed. As usual, the performance measure considered is the bit error rate for a given noise level. Als...
