“…To overcome the issue of time asynchronization due to highmobility, the effectiveness of the linear programming (LP) decoder with the ML application property is shown to be a very good choice to achieve close-to-optimal BER [42]. Sparse code spreading-aided multi-carrier differential chaos shift keying (SCS-MC-DCSK) transceiver is proposed by [43] and shown to provide reliable communications under different channel conditions. [44] compared the performance of filter shape index modulation (FSIM) with quadrature amplitude modulation (QAM) and quadrature phase shift keying (QPSK) in terms of filter index error and BER lower bound.…”

“…Compared to the traditional DCSK system, the MC−DCSK system achieves better spectral efficiency and more effective energy consumption while reducing inter-signal interference. In [22], a MC−DCSK system with sparse code spreading (SCS−MC−DCSK) is proposed to improve the efficiency and reliability of multi-user transmission. In [23], a multi-carrier chaotic modulation scheme is proposed, which has good robustness in time-varying underwater acoustic (UWA) channels.…”

A new multi−carrier orthogonal double bit rate differential chaotic shift keying (MC−ODBR−DCSK) communication system is presented in this paper. With two composite signals generated by an orthogonal chaotic signal generator as reference signals, 2M bits of information data are transmitted on M−channel subcarriers, improving transmission speed and energy efficiency. In addition, the receiver does not require a radio frequency (RF) delay circuit to demodulate the received data, which makes the system easier to implement. This paper analyzes Data−energy−to−Bit−energy Ratio (DBR) of the system. The bit error rate performance of the system is simulated to verify the impact of parameters such as chaotic maps, semi-spread spectrum factor, and sub-carrier number. At the same time, the bit error rate performance of the MC−ODBR−DCSK system is compared with traditional DCSK systems in Rician fading and additive Gaussian white noise (AWGN) channels.

“…Permutation index differential chaos shift keying (PI-DCSK) and differential permutation index differential chaos shift keying (DPI-DCSK) modulations were presented in [ 8 , 9 ], where a permutation is used to encode additional data with a list of codes referring to a series of chaotic references. Sparse codes were used similarly to achieve higher spectral efficiency for the Multi-carrier DCSK systems in [ 10 ]. In [ 11 ], time-reversal transform is combined with the DCSK design to improve the BER and spectral performances given a land mobile satellite channel model.…”

In this paper, we present a new multi-user chaos-based communication system using Faster-than-Nyquist sampling to achieve higher data rates and lower energy consumption. The newly designed system, designated Multi-user Faster Than Nyquist Differential Chaos Shift Keying (MU- FTN-DCSK), uses the traditional structure of Differential Chaos Shift Keying (DCSK) communication systems in combination with a filtering system that goes below the Nyquist limit for data sampling. The system is designed to simultaneously enable transmissions from multiple users through multiple sampling rates resulting in semi-orthogonal transmissions. The design, performance analysis, and experimental results of the MU-FTN-DCSK system are presented to demonstrate the utility of the newly proposed system in enabling multi-user communications and enhancing the spectral efficiency of the basic DCSK design without the addition of new blocks. The MU-FTN-DCSK system presented in this paper demonstrates spectral gains for one user of up to 23% and a combined gain of 25% for four (U=4) users. In this paper, we present a proof of concept demonstrating a new degree of freedom in the design of Chaos-based communication systems and their improvement in providing wireless transmissions without complicated signal processing tools or advanced hardware designs.
