The anti-noise semantic communication technology jointly developed by the Communication Technology Research Institute of the School of Information and Electronics at Beijing Institute of Technology (BIT) and China Unicom has provided strong support for the ongoing 9th Asian Winter Games in Harbin, which runs until February 14.

Generally, the environment of a hockey arena during the event, where the shouts of athletes, cheers from spectators, and live broadcasts inside the venue intertwined, could create an extremely complex communication scenario. Traditional communication methods struggle to cope with such a high-traffic and noisy background environment.

The remarkable cutting-edge technology - anti-noise semantic communication technology – has tackled this challenge.

The researcher tests the anti-noise semantic communication system in the ice hockey arena during the Asian Winter Games in Harbin.

This technology developed by BIT's team has achieved a breakthrough in high-definition voice communication between two machines and has been successfully tested in 5G networks and high-orbit satellite communication. It can be deployed in venues and emergency vehicles, achieving two major technological breakthroughs in low-bandwidth transmission and anti-noise communication.

Even in harsh conditions such as crowded sports venues and noisy environments, it can analyze real-time voice signals, effectively filter background noise, and achieve clear and stable communication, providing a new communication guarantee for sports events and emergency dispatch.

The core of this technology lies in AI "semantic understanding" and millisecond-level noise reduction capabilities.

Meanwhile, one of the highlights of this technology is its exceptional tolerance to extreme conditions. Even in scenarios with a high volume of concurrent users and adverse channel transmission conditions, it can maintain stable communication, achieving outstanding call quality and noise resistance performance.
