Disclosed herein are various embodiments of methods, systems, and apparatuses for sending and receiving signals in a digital communication system. In one embodiment performs steps of transmitting a signal from a device with a first antenna array and calibrating the signal with a phase shift of the signal. In one exemplary method embodiment, a signal is transmitted from a beam-forming transmitter to an assisting receiver in an IEEE 802.11 wireless transmission. A return calibration signal from the assisting receiver with information regarding the phase error of signal is received by the beam-forming transceiver. The beam-forming transmitter introduces a calibration phase error to cancel the phase error as reported by the assisting receiver.
