| 20100120381 | POLAR TRANSMITTER, METHOD AND APPARATUS FOR PHASE MODULATION - A phase modulation method with a polar transmitter. A target frequency is first designated by comparing the RF signal with a reference frequency and the phase sample. An oscillator control word is generated based on the target frequency.
