Fast Frequency-Direction Mapping Design for Data Communication With True-Time-Delay Array Architecture

In recent times, beamforming architectures utilizing True-Time-Delay arrays have gained significant interest in the field of wide-band data communication due to their abilities to generate frequency-dependent responses with great flexibility. This paper proposes a new heuristic fast algorithm with the goal of beamforming signals to different directions in different sub-bands. The proposed algorithm not only achieves better spectral efficiency than existing heuristic algorithms, but also significantly reduces computation time compared to optimization-based methods.
