Abstract
Systems, methods, and computer-readable media for receiver channel calibration are provided. The method includes generating a plurality of calibration signals corresponding to a plurality of receiver channels, respectively. The plurality of calibration signals are combined with a plurality of data signals, respectively, thereby generating a plurality of combined signals. The plurality of combined signals are propagated through at least portions of the plurality of receiver channels, respectively. The plurality of calibration signals are extracted from the propagated plurality of combined signals, respectively. At least two signal characteristics of at least two of the extracted plurality of calibration signals are compared. At least one adjustment in gain, phase, or timing for at least one of the receiver channels is identified based on a result of the comparing. Based on the identified adjustment, a data signal received via the at least one of the plurality of receiver channels is adjusted.
