Abd El-Samie © Springer Science+Business Media, LLC. 2010 Abstract In this paper, we propose a chaotic interleaving scheme for the contin- uous phase modulation based single-carrier frequency-domain equalization (CPM-SC- FDE) system. Chaotic interleaving is used in this scheme to generate permuted versions from the sample sequences to be transmitted, with low correlation among their sam- ples, and hence a better bit error rate (BER) performance can be obtained. The pro- posed CPM-SC-FDE system with chaotic interleaving combines the advantages of the frequency diversity, the low complexity, and the high power efficiency of the CPM- SC-FDE system and the performance improvements due to chaotic interleaving. The BER performance of the CPM-SC-FDE system with and without chaotic interleaving is evaluated by computer simulations. Also, a comparison between the proposed chaotic interleaving and the conventional block interleaving is performed. Simulation results show that, the proposed chaotic interleaving scheme can greatly improve the performance of the CPM-SC-FDE sys- tem. Furthermore, the results show that this scheme outperforms the conventional block E. S. Hassan · M. I. Dessouky · S. A. El-Dolil · F. E. A.
