Software defined radio based frequency domain chaotic cognitive radio
Chaotic communication system has attracted strong interests in high security communication due to robustness in multi-path fading environments, resistance to jamming, and low probability of interception. Recently, cognitive radio has emerged as a strong candidate to solve the spectrum congestion problem by operating over under utilized spectrum bands. Hence, it is highly desired to combine the security advantages of chaos communication with cognitive radio to create a chaotic cognitive radio communication system. However, traditional chaotic communication system is based on time-domain chaotic signal generator where the signal occupies one wide contiguous frequency band, making it inappropriate for cognitive radio applications. To apply the chaotic sequence onto cognitive radio to take advantage of multiple spectrum bands, we generate the chaotic signal in frequency domain. By applying a spectrum mask onto the chaotic signal in frequency-domain, a frequency domain non-contiguous chaotic waveform is created. In this paper, we use universal software radio peripheral and GNU radio software to implement and demonstrate a frequency domain chaotic cognitive radio. This demonstration has several unique features: (1) supporting real-time video transmission; (2) taking advantage of multiple non-contiguous spectrum bands; (3) dynamic cognitive radio waveform adaptation according to the primary user transmissions; (4) maintaining the security features of chaotic communication.
