Abstract EN
This paper investigates the antijamming performance of the NR-DCSK system.
We consider practical jamming environments including broadband jamming (BBJ), partial-time jamming (PTJ), tone jamming (TJ), and sweep jamming (SWJ).
We first analytically derived the bit error rates of the system under the BBJ and the PTJ.
Our results show that the system performances under these two jamming environments are enhanced as P increases, where P is the parameter of the NR-DCSK modulation scheme denoting the number of times a chaotic sample is repeated.
In addition, our results demonstrate that, for the PTJ, the optimal value of the jamming factor is close to zero when the jamming power is small; however, it increases and approaches one as the jamming power enlarges.
We then investigate the performance of the system under the TJ and the SWJ via Monte-Carlo simulations.
Our simulations show that single-tone jamming causes a more significant performance degradation than multitone jamming.
Moreover, we point out that the system performance is significantly degraded when the starting frequency of the sweep jammer is close to the carrier frequency of the transmitted signals, the sweep bandwidth is small, and the sweep time is half of the transmitted bit duration.
