Transmitter self-jamming analog cancellation

A device capable of object detection, comprising:

• a first transmit chain configured to transmit, via a first antenna, a transmit signal, the transmit signal being generated based on a mixer output signal;
• a first receive chain coupled to a second antenna and configured to receive a first receive signal, the first receive signal being associated with the transmit signal;
• a first phase shifter configured to generate a first phase-shifted signal based on an adjustment signal received via a signal path of the device coupled to the first transmit chain, the adjustment signal being generated based on the mixer output signal, wherein the first phase-shifted signal and the first receive signal are combined to generate a combined receive signal;
• and
• a control unit configured to control a phase-shift setting of the first phase shifter based on a mutual coupling component or a phase noise of the combined receive signal.

An apparatus for object detection by a device, comprising:

• means for transmitting a transmit signal, the transmit signal being generated based on a mixer output signal;
• means for receiving a first receive signal, the first receive signal being associated with the transmit signal;
• means for generating a first phase-shifted signal based on an adjustment signal received via a signal path of the device, the adjustment signal being generated based on the mixer output signal, wherein the first phase-shifted signal and the first receive signal are combined to generate a combined receive signal;
• and
• means for controlling a phase-shift setting associated with the means for generating based on a mutual coupling component or a phase noise of the combined receive signal.
