Abstract: 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.

Abstract: Exemplary embodiments are directed to systems, devices, and methods for mitigating effects of transmit signal leakage. A transceiver may include a transmitter and a receiver. The transceiver may further include a multi-tap analog adaptive filter coupled to each of the transmitter and the receiver and configured to generate an estimated transmit leakage signal based on at least a portion of a transmit signal from the transmitter and an error signal from the receiver.
