摘要

FM-DCSK is a non-coherent modulation and demodulation technique that uses chaotic signals as the carrier. Due to its inherent broadband nature, its good performance of anti-multipath-fading is promising for wireless communications. In order to improve the global performance of such chaotic communication systems, enhanced FM-DCSK based on the Woven convolutional code (WCC) is presented. Through system simulations, this article demonstrates that the WCC-based FM-DCSK system is superior to that of the traditional code-based FM-DCSK system and the original FM-DCSK system over AWGN, RAYLEIGH and RICEAN flat fading channels, especially with prominent coding gains over fading channels. It is further verified that there exists adaptability between FM-DCSK and channel coding. This finding will be significant for optimizing and analyzing the performance of the FM-DCSK system improved by good channel coding schemes, towards better applications of the chaotic communication technology in the future.
