Abstract

FM-DCSK is a non-coherent modulation and demodulation technique, the output of which has the inherent wide-frequency performance will cause the estimation interference and the bit error rate decline. This paper designs and implements Frequency-modulated Differential Chaotic Shift Keying (FM-DCSK)Communication system based on GNU Radio platform. In order to get FM-DCSK signal, it needs to combine the FM modulation with the DCSK system. The bit energy of signals remained stable by using FM modulation so that the BER performance in such system can be improved. Since the system is based on software defined radio (SDR) to perform in a real-time wireless transmission, the bitrate, bandwidth and central frequency can be modified at ease. The experimental performance are discussed and compared to the theoretical performance.
