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, comprising an embedded pilot analyzer that detects an embedded pilot in the digital receive signal and analyzes the embedded pilot to determine phase noise data, the digital self-interference canceller coupled to the digital transmit path and the digital receive path;
wherein the phase noise data is partially based on a self-interference component of the digital receive signal;
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;
wherein the digital self-interference canceller generates the digital self-interference cancellation signal according to a digital transform configuration;
wherein the digital self-interference canceller adapts the digital transform configuration based on the phase noise data.
