Abstract: Facing the challenge of communication business with huge traffic and connection demand in the B5G and 6G era, broadband dynamic multi-beam communication is one of the key candidates to be included in the next generation cellular systems and satellite communication systems, which utilizes the broadband characteristics of high frequency band and further taps spatial dimension resources, so as to improve quality of service (QoS). In this paper a broadband multi-beam wireless communication prototype system combined with dynamic multi-beam control is proposed, in which both base station side and user side are in consideration. On the base station side, hardware architectures including X86 universal servers, RFSoCs, RF phased array antennas and high-speed interfaces are implemented, available for dynamic multi-beam control and other baseband signal processing functions. Wireless baseband algorithms are implemented in a fusion computing architecture of X86 servers and FPGA. The unique features of this system are dynamic multi-beam forming, large bandwidth, high throughput and high development flexibility for algorithms. This prototype system will be of great significance to 6G oriented system development, as well as be applied in rapid development and verification of intelligent algorithms.
