Joint angle of arrival and channel estimation method

摘要

The estimation of the channel and direction of arrival of the transmitter and receiver signals has a first step of phase estimation of the signals received from different antennas (3001 to 300i), and a second step of estimation (320i) of the arrival angle producing the phase rotation (330i) the two steps being carried out together. A third estimation step finds the attenuation along the signal path from the estimated values of phase rotation along the arrival angle.
