Systems and methods are described for using a single wideband pilot signal to reduce a timing misalignment between receivers in a multiple-input multiple-output (MIMO) radio system. The multiple generators of the MIMO radio system may be aligned using a second wideband pilot signal subsequent to performing the receiver alignment. The calibration kit of the MIMO radio system may be aligned using a third wideband pilot signal prior to performing the receiver alignment. Alignment may be achieved to subsample precision by determining time delays from the rate of change of the phase shift of the wideband pilot signals.
