Systems and methods for non-linear digital self-interference cancellation
TL;DR: In this paper, 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 transmission signal of a full-duplex radio, a nonlinear transformer, a transform adaptor that sets the transform configuration of the nonlinear transform, and a post-processor combined the non-logical selfinterference signal with a digital receive signal of the fullduplex radios is presented.

Systems and methods for self-interference canceller tuning
TL;DR: In this article, a method for tuning an analog self-interference canceller includes detecting a tuning trigger, calculating a set of tuning parameters (the tuning parameters including complex weights for the set of taps of the analog selfinterference canceler) in response to the tuning trigger and applying the tuning parameters based on component calibration data.
Patent
Adaptive techniques for full duplex communications
TL;DR: In this article, the first analog radio frequency signal including a signal of interest and an interference signal caused by a second analog signal transmitted in full duplex over a channel from which the first analogue transmission is received, adjusting at least one of the analog signals and a portion of the second signal to enable at least a reduction or an elimination of the interference signal in an output analog signal.

The case for a network protocol isolation layer
TL;DR: It is argued that sensor network communication stacks should have an isolation layer, whose purpose is to make each protocol's perception of the wireless channel independent of what other protocols are running, and two key mechanisms the isolation layer must provide: shared collision avoidance and fair channel allocation.
