Abstract

Frequency-Modulated Differential Chaos Shift Keying (FM-DCSK) is a non-coherent modulation and demodulation technique, which uses a chaotic signal as the carrier. Due to the inherent broadband nature, its good performance of anti-multipath interference is quite promising in wireless communications. In order to improve the overall performance of this chaos-based system, LDPC (Low Density Parity Check) codes are proposed to use for enhancing the FM-DCSK communication system. Through system design and simulations, it is shown that the enhanced system is superior to that without LDPC codes by at least 8dB over an AWGN channel. Moreover, the longer the frame, the greater its coding gain.
