The finals of the Fourth“Golden Dolphin”Cup Network-Powered Underwater Acoustic Algorithm Challenge were recently held in Wuhan, Hubei Province. After multiple rounds of intense competition, Professor Fengzhong QU's team from ZJU Ocean College emerged victorious, securing first prize in the underwater acoustic detection and communication category and claiming top honors in the mid-frequency acoustic communication sub-category.

The Golden Dolphin Cup Networked Acoustic Algorithms Challenge stands as one of China's premier competitions in the field of electronic acoustic countermeasures, aiming to unite innovative research teams and advance the development and practical application of key technologies. In this competition, three doctoral students from Professor QU's team—Xinyi ZHOU, Yueyi QIAO, and Libo ZHOU—under the guidance of Associate Professor Jiang ZHU, addressed core challenges such as low peak-to-average ratio waveform design, time-varying complex acoustic communication environments, and extremely low signal-to-noise ratios. Through continuous iteration and optimization of waveforms and receiver processing algorithms, they proposed a comprehensive acoustic communication solution. In offline competitions using large-scale real-world data provided by the organizers, this solution secured first place by achieving the lowest error rate among all algorithms.

This marks the second consecutive breakthrough for Professor Fengzhong QU's team in this competition track, following their third-place finish in the intermediate frequency category during the previous event. Their improved performance demonstrates the ZJU Ocean College's solid research foundation and sustained innovation capabilities in underwater acoustic communication algorithm development and engineering practice.
