Design and Performance Analysis of an FM-QCSK Chaotic Communication System

摘要：

This paper presents an improved chaos-based communication method using FM-QCSK (Frequency Modulated Quadrature Chaos Shift Keying) technique. Frequency modulation of the continuous-time chaotic signal makes it possible to generate an inherent wideband signal with constant energy per bit. Quadrature chaotic modulation can obtain similar BER performance but higher data rate compared to the common DCSK (Differential Chaos Shift Keying) method. The performance of FM-QCSK system is analyzed in context of AWGN channel and multipath channel. Compared with conventional periodical carrier modulation methods, FM-QCSK scheme has strong immunity to the frequency selective fading, which is shown in the simulation results.
