SYSTEMS AND METHODS FOR NON-LINEAR DIGITAL SELF-INTERFERENCE CANCELLATION
First Claim
1. A system for non-linear digital self-interference cancellation comprising:
- a pre-processor communicatively coupled to a digital transmit signal of a communication system that generates a first pre-processed digital transmit signal from the digital transmit signal;
a non-linear transformer that transforms the first pre-processed digital transmit signal into a non-linear self-interference signal according to a transform configuration;
a transform adaptor that sets the transform configuration of the non-linear transformer; and
a post-processor that combines the non-linear self-interference signal with a digital receive signal of the communication system.

Abstract
A system and method for non-linear digital self-interference cancellation including a pre-processor that generates a first pre-processed digital transmit signal from a digital transmit signal of a full-duplex radio, a non-linear transformer that transforms the first pre-processed digital transmit signal into a non-linear self-interference signal according to a transform configuration, a transform adaptor that sets the transform configuration of the non-linear transformer, and a post-processor that combines the non-linear self-interference signal with a digital receive signal of the full-duplex radio.

13. A method for non-linear digital self-interference cancellation comprising:
-
receiving a digital transmit signal of a communication system; transforming the digital transmit signal into a non-linear self-interference signal according to a transform configuration;
wherein transforming the digital transmit signal comprises generating a first non-linear self-interference signal component and a second non-linear self-interference signal component, and combining the first and second non-linear self-interference signal components to create the non-linear self-interference signal; andcombining the non-linear self-interference signal with a digital receive signal of the communication system. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
