2019. Design and Verification of Wake-up Signal for Underwater Nodes. 2019 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC). :1–5.
The construction and improvement of the underwater acoustic network is the premise and guarantee for the development of the marine industry. Because the underwater nodes need to work for a long time, it is especially important to ensure that the nodes have a long standby capacity. In general, the node is in a low-power standby state waiting for a wake-up signal. When the node detects the wakeup signal, it will resume normal operation. In this paper, we propose a signal design based on the m-sequence. which can detect the hidden awakening signal in the complex environment with low SNR and small Doppler shift. Simulation and experimental data indicate that when the input SNR is as low as -11 dB and the signal has a small Doppler shift, the system can still achieve a detection probability of 100% and ensure that the false alarm probability is lower than 10-6.

2016. On the Probability of Finding a Receiver in an Ellipsoid Neighborhood of a Sender in 3D Random UANs. Proceedings of the 11th ACM International Conference on Underwater Networks & Systems. :51:1–51:2.
We consider 3-dimensional(3D) underwater random network (UAN) where the nodes are uniformly distributed in a cuboid region. Then we derive the closed-form probability of finding a receiver in an ellipsoid neighborhood of an arbitrary sender. Computer simulation shows that the analytical result is generally consistent with the simulated result.
