Abstract:
At an antenna array of a first communication device, a wireless signal transmitted by a second communication device is received. The first communication device calculates a plurality of oversampled matched filter values corresponding to the wireless signal, which correspond to i) different values of a signal delay corresponding to the wireless signal, and ii) different values of a phase corresponding to the wireless signal. The first communication device determines a local maximum of the plurality of oversampled matched filter values across different values of the signal delay and different values of the phase, where the local maximum corresponds to a component of the wireless signal that is first to arrive at the antenna array. The first communication device calculates an angle of arrival of the wireless signal at the antenna array using a value of the phase corresponding to the local maximum of the plurality of matched filter values.
