US Patent 9344038 Tri-phase digital polar modulator

Exemplary embodiments are related to a tri-phase digital polar modulator. A device may include a modulator configured to generate a primary phase modulated signal including the most significant bits (MSBs) of a modulated signal, a leading phase modulated signal including a first least significant bits (LSB) of the modulated signal, and a lagging phase modulated signal including a second LSB of the modulated signal. The device may also include a combination unit configured to add the primary phase modulated signal, the leading phase modulated signal, and the lagging phase modulated signal.
