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...

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...

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...

Differential Space Time Shift Keying for Dispersive Multi-user Scenarios using OFDM

Spatial modulation (SM) is a recently developed transmission technique that uses multiple antennas. The concept of SM is extended to both the space and time dimensions to provide a general shift-keying framework. A new modulation scheme called Differential STSK (DSTSK) scheme, assisted by the Cayley unitary transform is proposed to OFDM aided Multiple Input Multiple Output (MIMO) Communication ...

Design 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...
