Optimal blind GNSS beamforming architecture in the presence of gain/phase mismatch
Preview AbstractFor Global Navigation Satellite System (GNSS), adaptive beamforming techniques are critical to interference and multipath mitigation in various applications. The major problems with existing beamforming architectures are their Initial Measurement Unit (IMU) dependence and need for gain/phase calibration. In this paper, we proposed an optimal blind beamforming architecture that could achieve the maximum output signal-to-interference-plus-noise ratio (SINR) in the presence of gain/phase mismatch. The effectiveness of the proposed architecture is verified by theory analysis and simulation results.
