    • 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.

    • Methods and systems for equalization of a first receiver. A method may include receiving an input signal at the first receiver. The method may also include receiving the input signal at a second receiver. The method may further include determining, from an output response of the second receiver, an estimate of an out-of-channel interferer present in the input signal. The method may also include determining an estimate, of an undesired in-channel response of the first receiver to the out-of-channel interferer present in the input signal. The method may include applying the estimate, of the undesired in-channel response of the first receiver to the out-of-channel interferer present in the input signal, to an output signal of the first receiver to substantially cancel an instance of an undesired in-channel response of the first receiver to the out-of-channel interferer.
