Abstract: Chaotic communications have emerged as a promising candidate for future wireless networks. Out of several chaotic modulation techniques, CS-QCSK is the best in terms of QoS and spectral efficiency. Low complex RGR-GC has been identified to exhibit better error performance than any other STBC codes through our earlier investigations. The benefit of both the aforementioned schemes can be realised by a mere concatenation of them as a single physical layer entity. This paper attempts to study such a novel system through simulation analysis in terms of BER, spectral efficiency and capacity maximisation. The obtained results are found to be highly satisfactory in spite of marginal increase in complexity.
