Abstract
A wireless transmitter comprises an input configured to receive a data signal. A mixer mixes the data signal with a correction signal producing a corrected signal. The correction signal changes a phase in the data signal to compensate for a measured phase error at a desired receiver. A modulator modulates the corrected signal to radio frequency as a radio frequency signal. An antenna radiates the radio frequency signal.
