Systems and methods for phase noise mitigation
First Claim
1. A system for phase noise mitigated communication comprising:
- a primary transmitter, coupled to a digital transmit path of an electronic device, that converts a digital transmit signal received via the digital transmit path to an analog transmit signal, and transmits the analog transmit signal via an analog transmit path;
a primary receiver, coupled to a digital receive path of the electronic device, that receives an analog receive signal via an analog receive path, and converts the analog receive signal to a digital receive signal;
an analog self-interference canceller, coupled to the analog receive path and the analog transmit path;
wherein the analog self-interference canceller samples the analog transmit signal, generates an analog self-interference cancellation signal based on the analog transmit signal, and combines the analog self-interference cancellation signal with the analog receive signal; and
a digital self-interference canceller, coupled to the digital transmit path and the digital receive path;
wherein the digital self-interference canceller samples the digital transmit signal, generates a digital self-interference cancellation signal based on the digital transmit signal, and combines the digital self-interference cancellation signal with the digital receive signal; and
a secondary receiver coupled to the analog transmit signal path and coupled to an input of the digital self-interference canceller;
wherein the secondary receiver samples the analog transmit signal to produce and analog sourced digital signal;
wherein the digital self-interference canceller generates the digital self-interference cancellation signal based on the digital transmit signal and the analog-sourced digital signal.
