Design of a Digital Array Signal Processing System with Full Array Element

Abstract: For the application of a digital array signal processing system with a high sampling rate and large bandwidth, and considering the constraints of limited resources (performance, volume, power consumption, weight, etc.), this paper proposes a design and implementation method of broadband digital array signal processing system based on radio frequency system on a chip. The system focuses on multi-channel synchronization under a high sampling rate and multi-channel amplitude and phase calibration under large band… Show more

“…Direction of arrival (DOA) estimation is a widely studied topic in the signal processing area, which performs a key role in wireless communications, astronomical observation, and radar applications [1][2][3][4][5]. The conventional beamforming (CBF) method is a classical solution for DOA estimation.…”
