In-band full-duplex (IBFD) wireless systems offer the ability to revolutionize frequency spectrum utilization for future networks. For IBFD systems to work, the self-interference (SI) generated by each wireless node should be sufficiently mitigated, which becomes more challenging as the bandwidth increases. RF cancellation enables this interference reduction but has been limited so far to narrowband operation or restricted to distinctive environments. Fortunately, a photonic-enabled RF canceller can provide broadband interference cancellation using photonic components in a wideband vector modulator architecture with tunable time-delay taps. An example of this canceller with 20 canceller taps provides 25 and 20 dB of cancellation over 500-MHz and 1-GHz instantaneous bandwidths, respectively, and is tunable between 0.5 and 5.5 GHz. This photonic-enabled RF canceller provides the wideband operation and high tap counts for successfully deploying future wireless systems with IBFD technology.

Envelope tracking can be employed to reduce power consumption of a power amplifier, but envelope tracking can introduce nonlinearities to a power amplifier. These nonlinearities can manifest themselves as noise at the output of the power amplifier. Embodiments described herein provide techniques for characterizing a parameter indicative of power amplifier noise when envelope tracking is employed. Measurement of this parameter can permit power amplifier designers to decide whether to forgo envelope tracking if a power amplifier is too susceptible to such noise, redesign the power amplifier to improve compatibility with envelope tracking, or to employ distortion compensation circuitry to reduce the noise output by the power amplifier. Counterintuitively, this distortion compensation circuitry may involve increasing the power, such as the envelope tracking power supply. However, increasing the power may be a desirable trade-off for increased linearity.
