To implement the digital beamforming, we implemented a prototype of the digital beamformer on a FPGA, Xilinx RFSoC, which has on chip 8ch AD/DA converters. This slied shows the actual DSP circuit(RX part) on the FPGA. It just controls one I-Q stream contains up to 2048 subcarriers. Each subcarrier¡¯s phase and amplitude is fully digitally controlled and mixed to have beam gain. | |
