Patent Number Title Of Patent Date Issued
8131224 Delay, gain and phase estimation for measurement receivers March 6, 2012
Phase and gain of a transmit signal are measured at a transmitter by determining a first time delay having a first resolution at a measurement receiver between a reference signal from which the transmit signal is generated and a measured signal derived from the transmit signal by com
8009762 Method for calibrating a phase distortion compensated polar modulated radio frequency transmitte August 30, 2011
The present invention is a method for calibrating a phase distortion compensated polar modulated RF transmitter, which uses amplitude pre-distortion to compensate for phase distortion, called AMPM compensation. Some embodiments of the present invention may include a method for calibr
7877060 Fast calibration of AM/PM pre-distortion January 25, 2011
A system and method are provided for calibrating Amplitude Modulation to Phase Modulation (AM/PM) pre-distortion in a transmitter operating according to a polar modulation scheme. In general, phase modulation is disabled during transmission of an actual polar modulation signal. As a
