“…Hence, the BER of the PI-DCSK system is composed of the BER of the mapped bits P r map and the BER of the modulated bit P r mod . Therefore, the total BER P r M would be expressed as [30] P r M = n log 2 (M ) P r map + 1 log 2 (M ) P r mod .…”

Abstract-A new non-coherent scheme called Permutation Index Differential Chaos Shift Keying (PI-DCSK) modulation is proposed in this paper. This original design aims to enhance data security, energy and spectral efficiencies, compared to its rivals. In the proposed PI-DCSK scheme, each data frame is divided into two time slots in which the reference chaotic signal is sent in the first time slot and a permuted replica of the reference signal multiplied by the modulating bit is sent in the second time slot. In particular, the bit stream is divided at the transmitter into blocks of n + 1 bits, where n mapped bits are used to select one of the predefined reference sequence permutations, while a single modulated bit is spread by the permuted reference signal just mentioned. At the receiver side, the reference signal is recovered first, then all permuted versions of it are correlated with the data-bearing signal. The index of the correlator output with maximum magnitude will estimate the mapped bits, while the output content of the corresponding correlator is compared to a zero threshold to recover the modulated bit. Moreover, a new multiple access (MA) method based on the proposed scheme is described and analysed. Analytical expressions for the error performance in single-user and multi-user environments are derived for additive white Gaussian noise (AWGN) and multipath Rayleigh fading channels, respectively. Furthermore, the performance of the proposed PI-DCSK system is analysed and compared with other non-coherent chaotic modulation schemes and is found to be promising.Index Terms-Chaos-based communication systems, permutation index differential chaos shift keying (PI-DCSK), bit error rate (BER), non-coherent detection, multiple access (MA).

“…Thus, the error performance of MCIK-OFDM with the ML is affected mainly by the M -ary symbol detection error instead of the index detection error. Unlike the ML, (23) shows that the SEP of MCIK-OFDM with the GD relies on the accuracy of both the index and M -ary symbols detections, even at high SNRs. Corollary 1.…”

“…The MCIK-OFDM with hybrid low complexity greedy detection and multiple antenna diversity reception is proposed in [17]. The detailed survey of IM techniques can be found in [18], [19] It is noteworthy that most of existing works focus on the BER performance analysis for the ML detection [20]- [22], or for the energy detectors like the GD [23], [24], while little work on the SEP analysis for MCIK-OFDM has been done. In fact, existing expressions for the BER are not able to provide a comprehensive insight into the achievable diversity order and coding gain of system.…”

“…While the former method increases the hardware complexity of the transmitter, the latter uses the allocated spectrum with poor efficiency as many subcarriers are nulled at each transmission. On the other hand, in [10], [11] the authors propose for the first time an IM technique for SS schemes. This system, called code index modulation (CIM), aims to increase the data rate by mapping additional data in the indices of different codes, which are used for spreading modulated bits.…”

Abstract-In this work, a novel non-coherent modulation system named Commutation Code Index Differential Chaos Shift Keying (CCI-DCSK) is presented. In the proposed scheme, the benefits of index modulation (IM) are exploited so that the system energy and spectral efficiencies are improved. We are putting forward a CCI-DCSK scheme in which the reference sequence along with its corresponding data bearing orthogonal version are sent within the same time slot to enhance spectral efficiency. Specifically, at the transmitter p additional bits are mapped into the index of the repetition commutation which is performed on the reference signal for the sake of forming its orthogonal version. Furthermore, the modulated bit is spread by the corresponding commutated replica of the reference signal. The reference and orthogonal data bearing signals are then summed within the same time slot prior to transmission. At the receiver, the received signal is first correlated with all possible combinations of the commutated replicas in order to find the index of the correlator output with the maximum magnitude. Subsequently, the maximizing index is then used to estimate the mapped bits, while the output of the corresponding correlator is used to despread the modulated bit via a zero-threshold comparator. To complete the study, analytical expressions for the bit error rate (BER) are derived for both additive white Gaussian noise (AWGN) and multipath Rayleigh fading channels. Finally, performance results of the proposed CCI-DCSK scheme is compared with the state-of-the-art IM-based non-coherent chaotic modulations and is found to be superior and competitive.
