Patent ID: 8385469

Claim:
A transmitter comprising: a signal processor for receiving a baseband signal and generating a first quantized signal and a second quantized signal; a mapper for receiving the first quantized signal and the second quantized signal and generating a first plurality of control signals and a second plurality of control signals; a first phase selection array for receiving the first plurality of control signals and generating a first plurality of waveforms at a carrier frequency having a phase selected from multiple predetermined possible phases; a second phase selection array for receiving the second plurality of control signals and generating a second plurality of waveforms at the carrier frequency having a phase selected from multiple predetermined possible phases; a digital power amplifier array for receiving the first plurality of waveforms at the carrier frequency and the second plurality of waveforms at the carrier frequency, and generating an output signal; and an oscillator connected to the first phase selection array and the second phase selection array, the oscillator generating multiple phase signals, and wherein the first phase selection array includes a first plurality of phase selectors, each of the first plurality of phase selectors receiving the multiple phase signals and one of the first plurality of control signals, and either outputting an inactive signal, or one of the first plurality of waveforms at the carrier frequency having a phase corresponding to one of the multiple phase signals, based on the one of the first plurality of control signals, and the second phase selection array includes a second plurality of phase selectors, each of the second plurality of phase selectors receiving the multiple phase signals and one of the second plurality of control signals, and either outputting an inactive signal, or one of the second plurality of waveforms at the carrier frequency having a phase corresponding to one of the multiple phase signals, based on the one of the second plurality of control signals.
