Prof. Shun Zhang’s group from Xidian University：The 3.5GHz two-bit RIS aided communication system
The video shows the 3.5GHz two-bit RIS aided communication system from Xidian University. The main component of this sytem is the RIS sub-array with 16X16 elements, and can support upto 16 RIS sub-arrays. The beam scanning range of the RIS sub-array is ±60 °, and the 10Gbps high-speed GTX transceiver is utilized for the codebook refresh. The communication terminal with full protocol stack, which is developed by Xidian University, is adopted for the real-time collection and display of the comminication parameters. In indoor environment, the maximum beamforming gain of RIS is 18dB, and the maximum 13dB gain can be obtained compared with the metal plate. In the corridor environment, the average gain of 11dB can be obtained.
