AboutAbout the lab
Building fast and smart wireless communications
The Communications and AI Signal Processing Lab studies ultrahigh-speed wireless communications and the AI and signal processing that support them.
Communications is a field that underpins society, as seen in fifth-generation mobile communication systems (5G), which began in 2020.
To realize high-performance, highly functional communication systems, the lab takes a multifaceted approach: developing optimization and simulation tools, new communication methods, and new signal processing functions.
Key terms
- Signal processing
- Technology for extracting necessary information from signals such as radio waves and sound, or converting them into a form that is easier to handle.
- Fifth-generation mobile communication system
- A wireless communication system used in smartphones and other devices, offering higher speeds and larger capacity. It is called 5G.
- Simulation
- Reproducing and checking how a communication system works on a computer before building the real thing.
