A fundamental, omnipresent feature of the global information age is that cyber-capabilities, e.g. computing, communication and control, are inherently embedded in numerous physical/engineered systems from the nano-world to largescale systems-of-systems. Many scientific/technological challenges require intensive multidisciplinary studies, calling for new formulations, techniques and innovative solutions from a spectrum of communities in systems engineering/control/communications. IJSCC offers a vibrant discussion forum in this interdisciplinary area, especially communication systems augmented by control techniques and control systems whose components are interconnected via communication networks. Contents: IJSCC publishes original papers, review papers, technical reports, book reviews, notes and commentaries. Special Issues devoted to important and timely topics in integrated control and communication systems will occasionally be published.

In this paper, a chaotic communication system based on the combination of Improved–Differential chaos-shift keying (IDCSK) scheme and [Formula: see text] MIMO technique (2T2R), namely 2T2R-IDCSK, is investigated. We point out that there are differences in correlation characteristics between the conventional and time-reversed chaotic sequences. From this aspect, bit-error-rate (BER) performance of the system over an additive white Gaussian noise (AWGN) channel is analyzed taking into account the correlation effect of time-reversed chaotic sequences. BER expressions are verified by Monte-Carlo simulation. The obtained results prove that the 2T2R-IDCSK system performs worse under the correlation effect, however still dramatically outperforms the conventional [Formula: see text] MIMO-DCSK system.
