FPGA Implementation of Efficient 2D-FFT Beamforming for On-Board Processing in Satellites
DescriptionOn-board processing of digital beamforming in satellites is an efficient solution for the higher speeds, more capacity, and lower latency, but the limited power makes it impractical to digitally create thousands of beams at once. A significant portion of the analog hardware in a satellite communications payload can be replaced with highly integrated digital components, which are frequently more affordable and smaller by employing digital beamforming (DBF). Fast Fourier transform (FFT) methods can further reduce the computing cost of the DBF. This paper proposes and implements an area-power efficient 4-bit twiddle factor quantized 2D-FFT digital beamforming with optimization techniques.
