N2 - Analog beamforming with large-scale phased arrays is an attractive technology for long-range millimeter- wave (mmWave) communication. However, the beam squint will emerge when the signal bandwidth and the number of antenna increase. In this end, we develop a digital compensation wideband analog beamforming architecture to eliminate the beam squint. Specifically, we view the array response and the analog beamforming as a frequency-selective channel, which is compensated in the digital baseband. The signal direction is estimated to design the analog beamforming vector and the digital compensation values using the incoherent signal subspace (ISS) wideband direction-of-arrival (DOA) estimation algorithm with 1-bit quantization. Finally, simulation results indicate that the proposed algorithm is valid in the large-scale antenna arrays, and the beam squint effect can be eliminated effectively by the digital compensation method.
