Leveraging Waveform Structure to Develop a Power Scalable AoA Estimation
IEEE Open Journal of the Communications Society, 2021 In a mmWave mobile device, power consumption resulting from the high sampling rate is a primary concern for angle of arrival (AoA) estimation solutions. In this paper, we provide a power scalable solution for AoA estimation with structured waveforms in a
