This paper addresses the modeling and cancellation of self-interference in full-duplex direct-conversion radio transceivers, operating under practical imperfect radio frequency (RF) components. First, detailed self-interference signal modeling is carried out, taking into account the most important RF imperfections, namely, transmitter power amplifier nonlinear distortion as well as transmitter and receiver IQ mixer amplitude and phase imbalances. The analysis shows that after realistic antenna…

An Augmented Nonlinear LMS for Digital Self-Interference Cancellation in Full-Duplex Direct-Conversion Transceivers

This paper first analyzes the power of the SI components under practical conditions and focuses on the most significant one, which is proven to be produced by the I/Q mixer imbalance, and adopts a widely-linear digital SIC approach, which simultaneously deals with the direct SI and its image component caused by theI/Q imbalance.

Joint Digital Self-interference Cancellation in Full-duplex Radios under IQ Imbalance and Transmitter Non-linearity

The benefit of combining analog and digital cancellation is highlighted: if the former attenuates interference sufficiently well such that all received signals fit within the limited dynamic range of ADCs, the latter can handle the residual self-interference efficiently.

Analysis of Oscillator Phase-Noise Effects on Self-Interference Cancellation in Full-Duplex OFDM Radio Transceivers

The results show that phase noise has a severe effect on self-interference cancellation in both of the considered cases, and that by using the common oscillator in upconversion and downconversion results in clearly lower residual self- interference levels.

A self-interference cancellation scheme for full-duplex orthogonal frequency division multiplexing systems is proposed, which increases the amount of cancellable self- interference power by suppressing the distortion caused by the transmitter and receiver nonlinearities.

Full-Duplex Transceiver System Calculations: Analysis of ADC and Linearity Challenges

It is observed that the nonlinear distortion produced by the transmitter PA is a significant issue in a full-duplex transceiver and, when using cheaper and less linear components, also the receiver chain nonlinearities become considerable.

Experiment-Driven Characterization of Full-Duplex Wireless Systems

This work shows that the average amount of cancellation increases for active cancellation techniques as the received self-interference power increases, and shows that digital cancellation is more effective when applied selectively based on measured suppression values.
